High Sensitivity 1000mV/g IEPE Accelerometer A21C1000 Piezoelectric Accelerometer Acceleration Sensor
The A21C type side output accelerometer is an accelerometer with a built-in circuit that converts high impedance charge signals into low impedance voltage signals. It uses coaxial cables to simultaneously perform constant current source excitation input and signal output. Widely used in vibration control, drop testing, environmental testing, structural testing, product quality research, mechanical research, modal testing, and other vibration and impact dynamic testing fields.
