Axle Identifier Sensor(Linear type)

Embed piezoelectric sensors (such as piezoelectric ceramics) on the road surface. When the tire rolls over the sensor, the pressure causes the piezoelectric material to polarize, outputting a voltage signal proportional to the pressure (piezoelectric effect). The detector captures this voltage signal. When it exceeds the threshold, it is determined that the axle has passed.

Features: It can roughly perceive the axle load, has relatively low installation damage, but may cause fatigue problems due to long-term dynamic impact.
