The pioneer of  quartz high-pressure sensor technology is the Swiss company Kistler. Piezoelectric sensors made of piezoelectric quartz crystals can be used to measure vibration, impact force, and acceleration. Piezoelectric sensors require a charge amplifier to convert the signal into a voltage signal. The data collector converts the voltage signal into a digital signal and transmits it to the PC. The analysis software running on the PC can obtain various physical signals measured by the piezoelectric sensor.

WIM sensor is a force sensor with quartz components, specifically designed to measure the wheel and axle loads of road vehicles. Lineas Compact sensors have been optimized to provide cost-effective traffic data collection. When force is applied to the sensor, the quartz element generates a charge signal proportional to the applied force. The sensor needs to be connected to the Kistler WIM data logger. The WIM data logger converts the charge signals of all Lineas Compact WIM sensors into wheel, axle, and total vehicle weight, and exports vehicle classification information. A WIM data logger can cover up to 4 lanes.
