Creating 1000 times more power with submersible load measuring pins.

22/07/2016
“Our DBEP load measuring pins and DSCC pancake load cells were ideal to use in this marine application, as both can be readily customised, including dimensions and IP ratings, to make them fully submersible” says Ollie Morcom, Sales Director of Applied Measurements Ltd.

Ocean and tidal currents are a sustainable and reliable energy system. Minesto’s award winning product Deep Green converts tidal and ocean currents into electricity with minimal visual and environmental impact. Minesto’s Deep Green power plant is the only marine power plant that operates cost efficiently in areas with low velocity currents.

• Fully Customisable
• IP68 to Depths of 6500 Metres Available!
• Stainless Steel – Ideal for Marine Applications
Minesto needed to measure the strut force in Deep Green’s kite assembly. The measuring device needed to withstand permanent underwater submersion. “Our load measuring pin’s stainless steel construction and ability to be customised to IP68 submersion rating made this the ideal choice for use in Deep Green’s control system”, explains Ollie Morcom, Applied Measurements’ Sales Director. Their 17-4 PH stainless steel construction makes them perfect for marine and seawater applications. The DBEP load measuring pin was modified to have an IP68 protection rating to a depth of 30 metres and was fitted with a polyurethane (PUR) submersible cable and cable gland, ensuring the entire measuring system was suitable for this underwater marine application.

Deep-Green-cu-219x300The load measuring pin needed to fit within Deep Green’s control measuring system. The load measuring pin’s dimensions can be customised to suit a specific design. As Deep Green needed to retain its small and lightweight construction, the DBEP load measuring pin was manufactured to their exact dimensions, ensuring that it fitted within the control assembly without adding unnecessary additional weight to the structure, thus maintaining the efficiency of the Deep Green kite.

What is Deep Green?
Deep Green is an underwater kite assembly with a wing and a turbine, attached by a tether to a fixed point on the ocean bed. As the water flows over the kite’s wing, the lift force from the water current pushes the kite forward. The rudder steers the kite in a figure of 8 trajectory enabling Deep Green to reach a velocity 10 times faster than the water current, generating 1000 times more power. As the water flows through the turbine, electricity is produced in the gearless generator. The electricity is transmitted through the cable in the tether and along subsea cables on the seabed to the shore. Customised versions of our DBEP load measuring pins and DSCC pancake load cells are used within the control system of the kite.

• Fully Customisable
• Low Physical Height
•Optional: IP67, IP68 and Fatigue Rated Versions Available
• High Accuracy: <±0.05%/RC
Minesto also needed to monitor the varying tension load of the tether created by the wing. Using our high accuracy DSCC pancake load cells we were again able to make a custom design to fit into their existing assembly. Our pancake load cells are also manufactured from stainless steel and can be modified with alternative threads, custom dimensions, mounting holes, higher capacities and higher protection ratings. The DSCC pancake load cell used in Minesto’s marine power plant was IP68 rated for permanent submersion in seawater to 50 metres depth. The pancake load cells design delivers excellent resistance to bending, side and torsional forces and its low profile makes it ideal where a low physical height is required.

ICA2H Miniature Load Cell Amplifier
Within the pancake load cell we fitted a high performance ICA2H miniature load cell amplifier. The ICA2H miniature amplifier is only Ø19.5mm and 7.6mm high and is designed to fit inside a broad range of strain gauge load cells where a larger amplifier cannot. It has a low current consumption and delivers a 0.1 to 5Vdc high stability output. Using an integrated miniature amplifier kept Deep Green’s control assembly small and lightweight. The ICA2H miniature amplifier was chosen because of its high stability and fast response which is essential for the safe and efficient operation of Deep Green.

“We really enjoyed working with Minesto on this fantastic marine project.”

“We can deliver a complete tensile monitoring system in under 1 week! Don’t take our word for it, take Clark Masts’!”

Challenge – To Measure Larger Loads in Stainless Steel Guy Cables with a Super-Fast Delivery.

Clark Masts, a telescopic and sectional mast manufacturer, needed a way to accurately monitor the tensile stress in the guy cables of their newly developed super-heavy telescopic masts and they needed it urgently.

With head loads of up to 500kg and extended heights of up to 34m, the measuring instrument needed to accurately handle the larger head loads, taller heights AND be delivered in under 1 week!

“For our new larger mast range with large head loads we needed an instrument with a higher range up to 500kg and in a hurry, so that’s how we decided upon your product.” Gwyn Evans, Clark Masts Systems Limited. Here’s the story.

Tensile strength on guys

With huge capacities of up to 30,000kg and an accuracy of <±0.03% of the rated capacity, the highly accurate DBBSM S-beam load cell really is the knight in stainless steel armour. Not only can it efficiently handle the larger loads in the guys, it can also be supplied in less than 1 week! Its tough construction makes it ideal to use in the harsh outdoor conditions on the guy cables.

Rod Ends and Mounting Accessories
Clark Masts were supplied with a DBBSM-1000kg S-beam load cell and additional rod end bearings to enable effective tensile testing of the larger loads in the guy cables. The rod end bearings serve to:

  • Centralise the Tensile Force Through the Primary Axis.
  • Reduce any Extraneous Forces.
  • Improve Overall Performance and Accuracy of the Load Cell.

“By using the DBBSM S-beam load cell with the rod end bearings, Clark Masts increased the overall efficiency of their tensile monitoring system.” said Robert Davies, Applied Measurements‘ Production Director.

TR150 Handheld Display
Along with the DBBSM-1000kg s-beam load cell they also supplied a 7 digit LCD handheld indicator. The TR150 handheld indicator has an IP65 rating making it a perfect partner to the DBBSM S-beam load cell, as both can be used in the harsh outdoor environments of Clark Masts tensile testing. Its dual range function means the display can be calibrated in 2 different engineering units i.e. newtons and kg or can be used to calibrate 2 separate load cells using just 1 display. It is powered by 2x AA batteries which can last up to 450 hours of continuous use in low power mode.

Their DBBSM S-beam load cell can be supplied in less than 1 week and with our ex-stock TR150 handheld indicators mean we can offer a complete tensile monitoring system in under 1 week!

Besides healthcare and food, biosensor devices are penetrating the mobile, security and automotive segments, notes Frost & Sullivan

The biosensors market is proving highly attractive as it exhibits continuous growth in applications, penetration into newer sectors, and development of devices resulting in higher revenue year after year. The global biosensors space has seen the entry of multiple participants each year with none having exited the market so far.

Recent analysis from Frost & Sullivan, Analysis of the Global Biosensors Market, finds that the market generated revenues of $11.53 (€10.54) billion in 2014 which is estimated to more than double to $28.78 (€26.31) billion in 2021. Though innovation has facilitated biosensor penetration into a number of diverse markets, healthcare and food pathogen detection are currently the largest application segments.

“With health and wellness becoming a priority for all concerned in the value chain – individuals, governments, healthcare institutions, diagnostic device developers, system integrators, the medical fraternity and insurance companies – biosensors are acquiring more importance,” said Frost & Sullivan Measurement & Instrumentation Industry Principal Dr. Rajender Thusu. “For instance, strict food safety regulations enacted by federal governments to improve the health of consumers, require the use of biosensors for compliance monitoring.”

Under these regulations, meats, milk and milk products must be tested for the absence of a number of pathogens before being processed and supplied for consumption. Along with the rising trend of testing fresh vegetables and processed food for the presence of different pathogens, these norms are fuelling the adoption of testing kits.

Significantly, the use of biosensors is expanding to diverse end-user markets. While security agencies are using biosensors to detect drugs, banned substances and explosives, biosensors are also a valuable tool for monitoring health of soldiers.

Realizing the benefits, biosensor manufacturers have started to move to mobile platforms which will enable users to monitor key health parameters in real-time. Biosensor relevance in automotive applications will grow with the use of cognitive biosensors to boost driver alertness and enable safety.

Manufacturers must strive harder to meet the stringent and specific requirements of a number of industries such as wearable medical devices, food processing, environmental, bio-defense, and automotive.

Biosensor manufacturers must also look into other issues such as the long detection times associated with existing test methods in some applications. As samples need to be enriched in some cases before one can test for the presence of pathogens.

“Several companies are investing in R&D to innovate and improve biosensor technology, make it highly sensitive, and develop technology platforms to reduce detection time appreciably,” noted Dr. Thusu. “Since the long development cycle of biosensor devices is another challenge, manufacturers are trying to address this by deploying both optical and non-optical technologies.Rapid detection biosensor devices are the need of the hour for a number of applications.”

Further, manufacturers are developing nano-biosensors, with features to detect pathogens at a concentration as low as one cell per five milliliters of water. Advanced-stage research is also being conducted to create unique biosensors that can detect cell-to-cell interactions in therapeutic monitoring.
