Because of its light weight, the wheel load sensor WL 110 is easy to transport and can be used at any time without the need of ramps. Measurements are made on firm and level ground using levelling mats to ensure that all wheels of multiple axle systems are on the same level. As an alternative the sensors may be placed into a recess in the pavement. The depth must be the same as the height of the sensor to ensure that the platform surface is perfectly level to the pavement. Preferably the specially designed mounting frame is used.

In the normal case two sensors are used, one for the left, the other for the right track of the vehicle. The platform size is large enough so that the driver encounters little problems to pass the sensor within the active area. In case that the sensors are used for pre selection only, it is possible to work with one sensor measuring one side of the vehicle. The full weight is determined by doubling the results. Additional errors up to 5% may occur.

There is no display on the sensor. Its frequency signal is sent to the processing unit via the rugged cable. The further processing, visualisation and printout is performed by the connected processing unit EC 110 or by a personal computer with the software EC 200.
