Removable Axle Detection Resistive Sensor : RES2
The “Sensor / Support / Detector” set is designed for the detection of vehicle axles for a toll classification.
This set is used to detect vehicles travelling between 0 and 90 km/h (0 to 56 mph), with 99.9% detection accuracy.
Its shape also means that the sensor can slide into its SUP2 support directly in a toll lane. Replacing the sensor is easy and extremely fast during maintenance, so the toll lane can be reopened very quickly.
Axles are detected following pressure exerted by one or more wheels of the vehicle. This pressure therefore causes variation in the sensor’s electrical resistance. The signal is used by the Capella RD detector, which then transmits an “On-Off control” digital signal.
Key features :
Depending on the layout of RES2 sensors on the toll lane, different measurements may be provided, such as the detection of :
- Motorcycles (2 wheels),
- Reversing vehicles,
- Dual wheels.
