Piezoelectric weighing sensor : PE1O
The PE1O sensor is a ceramic piezoelectric sensor that delivers class I signals (7%). Once installed in the road surface, this sensor provides a signal for each axle of the vehicles moving over it.
These signals are then used by the HERA Road Traffic Analysis Station to provide measurements of weight – total, by axle, by axle group, etc.
This sensor is custom made at ECM’s premises. The length of the sensor is defined according to the width of the lane in order to cover its entire width.
With the HERA station, up to 4 piezoelectric sensors can be installed per lane.
Depending on the location of the sensors in the road surface, different data can be obtained.
