摘要:
A system for weighing a vehicle in motion is disclosed. One or more piezoelectric weight sensors produce charge outputs in response to the weight of a vehicle passing over the sensors. A charge amplifier converts the sensor outputs to a voltage level. A peak voltage detector detects the peak voltage, which represents the sum of all sensor outputs. The peak voltage is then converted to a weight value using the thickness sensitivity of the piezoelectric material.
