Product Details
Charge Amplifier Module For Weigh In Motion Sensor & WIM System
Product Description
The charge amplifier of the quartz crystal sensor can accurately
convert the charge signal generated by the quartz sensor under the
action of external force into a corresponding proportion of voltage
signal, and output the voltage signal to the weighing meter.
