Measuring precisely leads to knowing exactly
In the Netherlands, we are told, people live by the thought that measuring is the key to knowing. This grew from the wish to keep everything under control. Numbers don’t lie, so they measure everything. Even in the most popular sport in the Netherlands (and the world): soccer (sorry America!), voices are rising to take all variables in hand and rule out the factor of luck as far as possible.
Thus standardisation of circumstances is the solution! One of these standards is being achieved by making the field with artificial grass instead of the unreliable natural grass. When this grass then is measured in quality and other parameters, a “standard” field is on it’s way. This now is made possible by Deltec, in close corporation with Armac!
The number of football fields with artificial grass is steadily growing, but it is still an expensive commodity for most clubs as well as community or public sport providers. Natural grass needs a lot of attention but artificial grass is only optimised when it is installed correctly and adequately maintained. This is important in creating a perfect artificial field, that increases the pleasure of playing, lowers the chances of injuries and prolongs lifespan considerably.
But how is the quality of an artificial field determined? This light weight, handy, user friendly unit helps out sport clubs, sport sections of city and county councils as well as installation companies, which want to know the quality of the playing field. The Club Set gives values on:
• ball rolling
• vertical bounce of the ball
• infill level (thickness)
• shock absorption
• vertical deformation
• energy restitution and
• surface evenness.
Armac plays the ball
One of the devices within the Club Set is the Club Tester, which Armac has designed with extreme precision to measure the exact values of a simulated descent of a foot on the field and the particular behaviour of the artificial grass as it happenst. Due to high demands on the precision of measuring, the company used its creativity to its full potential in hardware and software engineering.
As a result, results that are accurately filtered from 10.000 variables in one second, in which the sensitivity of the acceleration sensor on 10 millivolt per G (falling force) must fall within a range between -200 and +200 G. “It took us quite some patience and accurate working to “catch” the highest and lowest values from such enormous range of data”, says software engineer Marcel van de Kamp of Armac all who as about the project.
The close cooperation between Deltec Metaal and Armac in the Netherlands has resulted in a way to compare easily the artificial grass field variables with the official FIFA guide lines, which are the international standard.
With the Club Tester a field is monitored and so injuries are minimized and the club enjoys longer a perfectly kept artificial grass field.
Maybe eventually we can predict exactly how the ball will role … or when a goal is not a goal or when a hand ball really ocurs
