Wireless lifting!

22/11/2019

New wireless control technologies are being adopted by manufacturers and users of cranes and other lifting equipment. Tony Ingham of Sensor Technology Ltd explains the advantages and looks at how the field is developing.

LoadSense

Trade Ship Harbored at Port of San Pedro, California, U.S.A.

Most of us find it odd to look back five or ten years to when our home computers were tethered to the wall by a cable. Somehow we just accepted that the cable restricted the mobility of the device and lived with that limitation. Now, of course, it is completely normal to pull a mobile phone out of your pocket and dial up the internet so that we can look up obscure information, book tickets or connect with a computer many miles away.

In the industrial and commercial arenas, wireless technology has revolutionised many practices. Logistics companies now routinely track the progress of every single parcel in their charge; field engineers collect data from and send instructions to remote facilities such as water pumping stations; customer accounts can be updated in real time, etc.
However, there is another aspect to wireless technology that is less obvious to the general public, but which engineers and technicians are really coming to appreciate. This may best be described as ‘local wirelessness’ or ‘wireless LANs (local area networks)’. Basically these remove to the need to install and maintain wiring for control equipment fitted to machinery such as cranes, hoists, lifts and elevators.

Control technology is essential to many modern industries, as it is the only practical way to ensure reliable operation and high efficiency.

Handling products through a busy working environment whether it is a container port, manufacturing plant, warehouse, logistics centre or retail outlet involves making sure that materials handling is rapid, accurate and safe. This requires a control system that can handle huge amounts of data in real time, can safely operate heavy duty machinery, and if necessary withstand extremes of climate and environment. Further, as many operations now run 24×7 there are likely to be immediate consequences to breakdowns and other stoppages, meaning control equipment has to be robust and reliable.

However the basic principles of a control system are relatively simple. The rotation of drive shafts in the various cranes and other machinery can be used to collect load and movement data on each item being moved. Each turn of the shaft will progress the equipment’s operation forward or backward a small but consistent amount, and if you can also measure the torque (rotational strain) in the shaft you can calculate the weight of the load being transferred.

This raw data stream can be used to easily calculate operational information such as the amount of goods or product moved, the time to completion of each operation, and the destination of each load. It is also equally easy to convert this operational data into commercial information and safety reports that include cumulative operating hours, total load lifted and other statistics.

In the past taking measurements from drive shafts has been difficult, but TorqSense, from Sensor Technology, provides a perfect solution. Previously, it was necessary to install sensors in difficult to access parts of industrial machinery and wire them back into the communication network that connected with a computer for collecting and interpreting the data. And once installed, the wiring had to be protected from damage and replaced if it failed.

However TorqSense gets around this by using radio transmissions instead of wiring. Further, old fashioned torque sensors tended to be delicate because they needed a fragile slip ring to prevent the turning drive shaft from pulling the wiring out of place, whereas TorqSense uses a wireless radio-frequency pick-up head that does not need physical contact with the rotating shaft.

A practical attraction of TorqSense is that its wirelessness makes it ultra-simple to install and robust in use. Furthermore it is largely unaffected by harsh operating environments, electromagnetic interference, etc. It is equally at home measuring coal on a conveyor, working on a dockside crane weighing and counting containers or in any other lifting application.

TorqSense is proving popular with an increasing number of users across many fields – not only in lifting, but also in robotics, chemical mixing and automotive applications – almost anywhere that uses machinery with rotating drive shafts.

Sensor Technology has also developed a complementary range of sensors, which measures the straight line equivalent to torque. Called LoadSense, this too uses a wireless radio frequency pick-up to collect data signals from the sensing head and transmit them wirelessly to a receiving computer for analysis.

It is notable, that both TorqSense and LoadSense can be used in a fully wireless mode, but equally can be fitted into conventional cabled systems, so is easy to retrofit into existing control systems.

It is also interesting to know that LoadSense was actually developed at the behest of a particular customer, a helicopter pilot who wanted real-time and exact information about the weight of loads he was carrying from an underslung cargo hook. The issue for him was that he would invalidate his helicopter’s certificate of airworthiness if he drilled a hole in the fuselage for a cable, so he had to have a wireless solution. This application also required very robust hardware that could withstand heat and cold, extreme movements and shock loads and be unaffected by motor noise, radio interference etc – all characteristics that translate well into fields such as lifting, conveying and cranage.
TorqSense, LoadSense, wireless data transfer and communications are making an increasing contribution to the development of materials handling technologies. While they are ‘invisible’ to the casual observer, they have the capacity to revolutionise many aspects of lifting operations and to drive efficiency, reliability and safety to new levels.

Connecting, communicating and creating in Netherlands.

14/03/2018

The country of the Netherlands is where the Rhine enters the sea. It is a country which has physically built itself out of the inhospitable North Sea. Often called Holland – which is the name of one (actually two) of its provinces – it even more confusingly for the English speaking world inhabited by the Dutch speaking Dutch. If you really want to know more about Holl.. er sorry, The Netherlands watch the video at the bottom of this piece.

Although not officially the capital of The Netherlands, Amsterdam is, The Hague is the seat of Government and official residence of the King. It was selected by the Emerson User Group as the venue for their European, Middle East & African assembly, refereed to as #EMrex on twitter. These assemblies – can we say celebrations? – occur every two years. The last was held in Brussels, the capital of the neighbouring Kingdom of the Belgians and of the European Union. An sccount of happenings there are in our postin “All change at Brussel Centraal.” (18/4/2016)

Lots of pictures from the event!

The size of this event was in marked contrast to the Brussels meet which was overshadowed by the terrible terrorist attacks in that city only three weeks earlier which presented transport difficulties. This time there were over one thousand six hundred delegates filling the huge hall of the Hague Convention Centre.

Another difference referred to in many of the discussions both formal and informal were the two great uncertainties effecting all businesses and industries – the possibility of a trade war with the USA under its current administration and nearer home the aftermath of the BREXIT decision – the exit of the British from the largest economic bloc on the planet. Many developments have been put on the long finger pending clarification on these issues.

Mary Peterson welcomes delegates

Why are we here?
This event continued in the vein of previous meetings. The emphasis continuing to move to perhaps a more philosophical and certainly a more holistic view of how the automation sector can help industry. This was made clear in the introductory welcome by Novartis’s Mary Peterson, Chair of the User Group, when she posed the question, “Why are we here?”

“This is a conference for users by users.” she said. It is a place to discuss users’ practical experiences; continuing our profissional development; learning best practice and proven solutions and technology roadmaps. But above all it presented an opportunity to connect with industry leaders, users and of course Emerson experts.

and on Twitter #EmrEx

The emphasis is on the totality of services and packages not on individual boxes. Emerson’s European President Roel Van Doren was next to address the assembly. We should know our plant but be unafraid to use expertese and knowledge to keep it fit for purpose. Monitor the plant constantly, analyse what is required and then act. This means seeing how the latest advances might improve production. This means harnessing the “new technologies.” In passing he drew our attention that Emerson had been recognised earlier this year as ‘Industrial IoT Company of the Year’ by IoT Breakthrough.

The path is digital
A very striking presentation was given by Dirk Reineld, Senior VP Indirect Procurement with BASF. He brought us to the top of Rome’s Via de Conciliazione on 19th April 2005. We saw the huge crowd looking towards the centre balcony as the election of a new pope was announced. He then moved forward to the 13th March in 2013, the same place but what a difference in such a short time. This time it seemed that everybody had a mobile phone held to take photographs of the announcement of the election of Francis. All we could see was a sea of little screens. He used this to emphasize a point “We are underestimating what is happening & its speed.” This is not helped by a natural conservatism among plant engineers. Change is happening and we either embrace it or get left behind. It is becoming more and more clear that in front of us “the path is digital!” He presented some useful examples of digitalisation and collaboration at BASF.

PRESENTATIONS

Registered delegates have access to slides from the main presentation programme. These slides are available for download via the Emerson Exchange 365 community (EE365).

Emerson Exchange 365 is separate from the Emerson Exchange website that presenters & delegates used before Exchange in The Hague. So, to verify your attendance at this year’s conference, you must provide the email you used to register for Exchange in The Hague. If you are not already a member of EE365 you will be required to join.

To access the presentations, visit The Hague 2018 and follow the prompts. The first prompt will ask you to join or sign in.

Something in this particular EmrEx emphasised how things are moving and those unprepared for the change. Among some of the press people and others there was disappointment expressed that there was not a printed programme as in previous years. This correspondent is used to going away into a corner and combing through the printed agenda and selecting the most relevant sessions to attend. This was all available on line through the “Emerson Exchange Web App.” This was heralded as a “a great preshow planning tool.” All we had to do was enter a link into our our web-browser on our phones and away you went. Yes this is the way to go certainly and although I am inclined to be adventurous in using social media etc I and some (if not many) others found this a step too far to early. It was not clear that a printed version of the programme would not be available and the first hour of a conference is not the best time to make oneself au fait with a new app.

Having said that while many of the journos took notes using pencil and paper they were not adverse to taking photos of the presentation slades so they could not be said to qualify as complete luddites!

Terrific progress but…

Rewards of efficiency
This event was being held at the same time as CERAWeek 2018 in which Emerson was an important participant. Some Emerson executives thus made the trans Atlantic journey to make presentations. One of those was Mike Train, Emerson’s Executive President who delivered his talk with no apparent ill effects. In effect he was asking a question. “Just how effective is progress?” Yes, we HAVE made phenomenal progress in the last 30 years. “Modern automation has made plants more efficient, reliable and safer, but, the ‘Efficiency Era’ is reaching diminishing returns….Productivity seems to be stagnation while the workforce is stretched.”

He postulated five essential competancies for digital transformation.

  1. Automated workflows: Eliminate repetitive tasks and streamline standard operations.
  2. Decision support: Leverage analytics and embedded exportise.
  3. Mobility: Secure on-demand access to information and expertese.
  4. Change management: Accelerate the adoption of operational best practices.
  5. Workforce upskilling: Enable workers to acquire knowledge and experience faster.

Making the future!

Making the future
The next speaker was Roberta Pacciani, C&P Manager Integrated Gas and Upstream Technology with Shell. She is also President of the Women’s Network at Shell Netherlands. She spoke on leveraging the best available talent to solve future challenges. I suppose that we would have classified this as a feminist talk but of course it isn’t. As the presenter said it is not so much a feminist issue as a people issue. “Closing the gender gap in engineering and technology makes the future.”  This was a useful presentation (and in this correspondent’s experience unusual) and hopefully will be helpful in changing perceptions and preconceptions in STEM and our own particular sector.

As partof EmrEX there is an exhibition, demonstration area. Delegates may see innovative technologies applied to their plant environment. They meet with experts about topics such as getting their assets IIoT ready or how to use a Digital Twin to increase performance and explore options to prepare their plant for the future. As a guide – printed as well as on-line – the produced a Metro-like guide.
Using this we could embark on a journey through products, services and solutions where Emerson together with their partners could help solve operational and project challenges.

One of the most popular exhibits was the digital workforce experience. Here we visited a plant and were transported magically to former times to see just how different plant management is now and particularly with the help of wireless and digitisation.

It happened!

One of the good things about this sort of event is the opportunity to meet friends for the first time though social media. Sometimes one does not know they are attending unless the tweet something. Thus I realised that an Emerson engineer was present and so I went looking for him in the expos area. This it was that Aaron Crews from Austin (TX US) and I met for the first time after knowing each other through twitter & facebook for a frightening ten years. Another of these virtual friends, Jim Cahill, says, “It hasn’t happened without a picture!” So here is that picture.

The following morning there were a series of automation forum dedicated to various sectors. The Life-Sciences Forum was one which was very well attended.  Ireland is of course a leader in this sector and we hope to have a specific item on this in the near future. Emerson have invested heavily in the national support services as we reported recently.

Each evening there were social events which provided further opportunities for networking. One of these was a visit to the iconic Louwman Transport Museum where reside possibly the largest collections of road vehicles from sedan chairs through the earliest motor cars up to the sleekest modern examples. These are all contained in a beautiful building. The display was very effectively presented and one didn’t have to be a petrol-head – and believe me there were some among the attendance – to appreciate it.

It is impossible to fully report an event like this in detail. One can follow it on twitter as it happens of course. And there will be copies of many of the presentations and videos of some of the sessions on the website.

The Emerson User Group Exchange – Americas will continue “spurring innovation” in San Antonio (TX USA) from 1st to 5th October 2018. It looks exciting too.

We promised at the top of this blog an exposé of the country often called Holland in English –

Electric vehicle pioneer favours wireless test rigs.

12/02/2018

A company that has been at the forefront of electric vehicle design and development for over 20 years has supplied a test rig based on a wireless torque sensor to a world renowned British University automotive research facility.

Tirius has been built on pioneering work on an all-electric single seat racing car and a series of record breaking vehicles. It continues to bring the latest technology to clients in the form of product design and development and the provision of its range of electric drive systems.

Head of Tirius, Dr Tim Allen, explains: “We are helping the university’s research team develop electric drive train technology typically found in ‘A-Class’ cars, for example urban runarounds and small family hatchbacks. Specifically we are currently looking at permanent magnet traction motors in a number of sizes and configurations, with a view to optimising electronic control for each motor type.”

The research involves running each motor on a test rig through its full output range and mapping its torque output at many points to build up a performance profile. The design of the controller can then be matched to the motor characteristics. This should be able to ensure that the motor runs in its optimum operating zone as much as possible, maximises motor life and regenerative braking, minimising wear, and is as energy efficient as possible.

The design of the test rig is in fact quite simple, thanks to the torque sensor, a TorqSense, as made by Sensor Technology.

“We are pleased to promote TorqSense and the guys at Sensor Technology,” says Tim. “We have been using their kit for many years and in many different roles. The bottom line is that they are easy to use, accurate and great value – partly because they can be re-used once their original project has been completed.

TorqSense is a good choice for this work because its non-contact operation allows rapid set-up during the profile building test runs. It also means extra drag forces are not added to the system, so measurements represent true values and calculations are therefore straightforward.”

TorqSense uses two piezo-electric combs which are simply glued to the drive shaft at right angles to one another. As the shaft turns it naturally twists along its length very slightly and in proportion to the torque, which deforms the combs changing their piezo-signature. This change is measured wirelessly by a radio frequency pick up and is a measure of the instantaneous torque value.

Its data is output to a very user-friendly computer screen which uses graphics to aid easy interpretations. In fact the display on the computer is similar to a car’s dashboard, so most people understand it intuitively. Further, the data is automatically logged for further analysis.

Tim again: “With our type of research work there are some potential errors that we have to look out for, including time-based zero-drift, bending moments on the shaft, bearing losses, temperature fluctuations etc. These are easily accounted for with TorqSense-based test rigs. Normally you have to account for the drag caused by the slip rings, but the wireless TorqSense does not use them, so that is one less calculation – and one less fiddly fixing task.

“A great benefit of TorqSense is the ease with which it can be mounted and dismounted, which simplifies research work where frequent reconfiguring is required.”

The University project will take two or three years to complete and the TorqSense test rig will be worked hard during this time. “At the end of the work, I have no doubt that the TorqSense will be reused in a new research program. It’s what we do in-house at Tirius.”

Ensuring pure air in Scottish towns.

15/01/2018

In North Ayrshire, Scotland, monitoring activities have demonstrated that the main local air quality issues are related to traffic congestion caused by a section of the High Street in Irvine, which is being used as a bus terminus, and by queuing traffic at New Street in Dalry. In both locations the pollutant of most concern is Nitrogen Dioxide.

Sensor on street in Irvine.

North Ayrshire Council operates a fixed continuous air quality monitoring station (AQMS) in Irvine High Street which supplies data to Scottish Air Quality website.

“Data from the AQMS is supplemented by portable monitoring equipment that is installed at key locations,” reports the Council’s Willie McNish. “Passive diffusion tubes provide approximate monthly average data, but over the last 2-3 years we have started using AQMesh air quality monitors. Three ‘pods’ have been installed in pollution hotspots and a further AQMesh pod is used as a mobile device; installed temporarily in key locations to assist with air quality strategy development, and planning and development control.”

AQMesh air quality monitoring pods, from Air Monitors, are small, lightweight, wireless, battery or solar -powered air quality monitors that are quick and easy to install. They are able to monitor the main pollutants simultaneously, delivering accurate cloud-based data wirelessly via the internet. “We use the AQMesh pods for air quality screening,” reports Willie McNish, one of the Council’s Officers responsible for air quality monitoring. “The beauty of these monitors is that they provide almost real-time data that we can access via PC. This is really useful for detecting and predicting trends. For example, I can look at the current air quality measured by a pod and then look at the Met Office website for information on wind speed and direction, and this helps us to better understand the factors that affect air quality.”

The ease and speed with which AQMesh pods can be installed in almost any location is a major advantage in air quality investigations related to planning applications. For example, Willie says: “Concerns about dust and fumes from trucks were raised in connection with an application to extend the life of a landfill site by ten years (as less waste is being landfilled more time was required to fill it), but by locating an AQMesh pod (measuring gases and particulates) in an appropriate location, we were able to support the planning decision by demonstrating that air quality would not be harmed by the extension.”

Monitoring is also informing the development of traffic management strategies to reduce exposure to air pollution. In Irvine, Willie says: “The prevailing wind direction is from the South West, which creates a canyon effect, whereby air pollution accumulates within streets that are confined by buildings on both sides. This effect is exacerbated by queuing double-decker buses, so we plan to undertake remedial measures and monitor their effects.”

As a consequence of the elevated levels of Nitrogen Dioxide in Irvine, the Council will undertake public realm works (streetscape improvements) to widen the pavement, and one of the bus stops will be relocated. This will not only move the source of pollution away from the receptor, but also allow better dilution and dispersion of pollutants, without affecting the frequency of service or convenient access to public transport. In Dalry, a new bypass is due to be constructed and it is anticipated that this will lower Nitrogen Dioxide levels. In both locations, modelling has indicated that air quality will improve, but existing monitoring data will be compared with data once the work is complete, so that an effective evaluation of the effects on air quality can be performed.

Summarising the advantages of the Council’s air quality monitoring strategy, Willie says: “The AQMS in Irvine employs standard reference methods or equivalent, to measure air quality, so it is able to provide definitive data for comparison with EU limits. The station is serviced and maintained by Air Monitors and delivers extremely high levels of data capture. Since 2015 it has also included a FIDAS 200 particulate monitor, so we are now able to monitor TSP, PM10, PM4, PM2.5, PM1 and Particle Number simultaneously, which provides greater insight into the types of pollution and their likely sources.

“To complement the AQMS we also operate 4 AQMesh pods which provide the flexibility we need to monitor air quality in precisely the location of greatest importance. Web connectivity combined with Air Monitors’ reliability of service provides us with continuous access to accurate air quality data, which means that we are able to fulfil our statutory obligations as a Council, and also find ways to protect the health of people in North Ayrshire.”

Celebrating Northern Europe’s Automation Engineers Engineering.

08/12/2017

NIDays welcomed hundreds of delegates from across Northern Europe to the historic Sandown Park Racecourse in England in November 2017, for its annual conference and exhibition. Each event was designed to educate and inspire the engineering community. Delegates to NIDays were given exclusive access to innovative technologies and could explore NI’s latest software, in a full day of keynote speeches, technical presentations and hands-on sessions.

Northern European Engineering Impact Awards
The night before, some of Northern Europe’s best engineers attended the prestigious Engineering Impact Awards.  The well-respected Engineering Impact Awards celebrated the most innovative engineering applications based on NI hardware and software.

Coventry University’s Dr Bo Tan won ‘Application of the Year’ for his system that combines passive WiFi sensing hardware and machine learning algorithms to monitor the health, activity and well-being of patients within nursing homes, allowing staff to improve their levels of efficiency and care.

Other winners include:

Advanced Manufacturing: Paving the Way for Industry 4.0 with Smart, Reconfigurable Manufacturing Machines
Biomedical: Combining Passive WiFi Sensing and Machine Learning Systems to Monitor Health, Activity and Well-Being within Nursing Homes
Education: Teaching Electronics to the Next Generation of Engineers using VirtualBench
Innovative Research: Unlocking Fusion Energy – Our Path to a Sustainable Future
Test and Validation: Saab Elevates Testing of the World’s Most Cost-Effective Fighter Plane
Wireless Communication: Using the LabVIEW Communications System Design Suite to Increase Spectral Efficiency for Wireless Communication

“The Northern European EIA’s were incredible this year. The breadth of applications showed what our products can do in the hands of world-class scientists and engineers!” says Dave Wilson, Vice President – Product Marketing for Software, Academia and Customer Education.

NIDays
Professors, researchers and design engineers were amongst the audience of the morning keynote ‘Testing and Deploying the Next Generation of Technology’ hosted by NI VP Dave Wilson. In this session, NI experts explained how the NI platform is accelerating innovation in applications ranging from transportation safety to the IoT.

During the afternoon keynote, Stuart Dawson, Chief Technology Officer at the University of Sheffield’s (GB) Advanced Manufacturing Research Centre (AMRC) was welcomed to the stage to discuss how super-trends like Industry 4.0, energy and the electrification of transportation are changing the way we live and work. Charlotte Nicolaou, Software Field Marketing Engineer, walked through how NI are continuing the LabVIEW legacy with the evolution of the world’s most productive and efficient engineering software, introducing LabVIEW NXG 2.0 and other new software releases including NI Package Manager.

Delegates had a chance to ‘dirty their hands!’

Delegates also had the opportunity to view application specific demonstrations that showcased the latest NI products and technology in the Expo Area, with plenty of NI engineers on hand to discuss their engineering challenges and technical questions. Participants also enjoyed an array of track sessions that included LabVIEW Power Programming and Test & RF Hands-On, giving users the opportunity to learn practical skills and network with specialists and peers.

Throughout the day, several guest presenters took to the stage including Jeff Morgan and Garret O’Donnell of Trinity College Dublin (IRL) and Niklas Krakau from Saab Aeronautics who discussed their incredible application enabling efficient testing of the world’s most cost-effective fighter plane, the Saab Gripen E.

Attentive Audience!

“NIDays allows us to highlight game-changing industry trends, whilst unveiling new, innovative technologies. However, it is the attendees, presenters, partners and exhibitors that provide the conference’s true highlights. What was my favourite part of the day? Learning how Coventry University is using WiFi signals to wirelessly monitor patient health through-walls? Meeting elite researchers and heads of industry during the dedicated networking sessions? Taking a tour of Cardiff University’s historic race car? Or sampling a ‘perfect pint’ of ale, courtesy of the robot bartender from Leeds University? NIDays was packed with inspiring moments and experiences that I will remember for a long, long time to come” says Richard Roberts, Senior Academic Technical Marketing Engineer.

12 exhibitors joined the lively atmosphere of the main exhibition hall, including Amfax, Austin Consultants and The Formula Student Silverstone 2017 winners, Cardiff Racing, who proudly displayed their history making Formula 1 car. Many more NI customers and partners filled the hall with their impressive applications, some of which won awards at the Engineering Impact Awards the previous evening.

Disinfection robot with robust wireless access.

31/10/2017

STERISAFE-Pro is a disinfection robot from the Danish company INFUSER. It disinfects surfaces in any given room – for example patient rooms, operating theatres or hotel rooms – removing up to 99,9999% of pathogens. The robot fills the designated room with an Ozone-based biocide agent which kills unwanted bacteria, viruses and fungi, while purifying the air from small particulate matter in the air. STERISAFE-Pro is controlled from outside the room using wireless technology from HMS Industrial Networks.

The unit produces Ozone (O3) by using the oxygen (O2) already present in the room. All that is needed is electricity and water. By diffusing Ozone and a fine mist of water, it is possible to expose all surfaces in a room. The Ozone oxidizes the membrane or shell of bacteria, viruses and fungi, leading to total deactivation of these micro-organisms.

The Ozone-saturated atmosphere in the room is sustained for a defined period of time, during which the pathogenic micro-organisms are killed on surfaces and in the air. Ozone naturally turns back to Oxygen after having reacted with pathogens and other pollutants, leaving no chemical residue.

Robust wireless access needed
Although ozone is a naturally occurring gas, it is harmful at high concentration levels and the STERISAFE-Pro requires that the operator is outside the sealed room while the robot runs its cycle. The operator uses a tablet which is connected wirelessly to the PLC inside the robot. INFUSER has created an app which the operator uses to control the robot. The app interfaces with the built-in webserver in the PLC.

OK, so that sounds easy enough, but accessing a PLC which is inside a hermetically sealed, stainless steel machine which performs surface disinfection, demanded a wireless solution with high performance.

Thomas Clapper

“When we first started developing STERISAFE-Pro, we used a regular commercial access point, but we soon realized that we needed something more robust and advanced,” says Thomas Clapper, production responsible at INFUSER.

“We needed an access point that was omni-radiant and also 100% sealed. This is when we came across the Anybus Wireless Bolt from HMS Industrial Networks.”

The Anybus Wireless Bolt™ is a wireless access point for on-machine mounting. It can communicate via WLAN or Bluetooth up to 100 meters and is built for harsh industrial conditions both when it comes to the physical housing and the wireless communication.

It was a perfect fit for STERISAFE.
“We use WLAN to communicate between the PLC inside the robot and the tablet and really benefit from the robust communication that the Wireless Bolt offers. We also needed to design unique connections for each robot/tablet-pair, so that it is possible to run several machines in the same area without radio interference. This is also something that the Anybus Wireless Bolt allowed us to do.”

Wireless Bolt

Tough demands
But the project has not been without challenges. One issue that INFUSER ran into was that Ozone sets tough demands on durability. Although the Wireless Bolt is IP67-classed (meaning that it is waterproof down to 1 meter’s depth), INFUSER still found that the rubber washer on the Bolt was not Ozone proof.

But since the Anybus Wireless Bolt is mounted in a standard M50 hole, it was easy to find a replacement – a washer that HMS now can offer as an alternative to their offering too.

“Implementing the Wireless Bolt was very smooth indeed,” says Thomas Clapper. “We had communication set up in a matter of minutes and have really not had any issues when it comes to the wireless communication. The Wireless Bolt is simply a very reliable and sturdy wireless solution.”
