Weighing Sensor & Axle Sensor & Weight-In-Motion System-30000KG
Quartz sensor converting dynamic tire force into electric signals, then the signals converted to analog voltage through the charge amplifier, and then through the A/D converter converting the analog signal to digital signal, finally the weighing result obtained by the embedded computer and its software. The measurement chain signal form and units are:
Force(N)→Charge(pC)→Voltage(V)→Sampling and operation→Weight(Kg)
