Piezoelectric Velocity Sensor
Piezoelectric Velocity SensorBased on piezoelectric accelerometers, the CV-YD-series have the extra character of built-in precise circuit of integration and velocity output. Wider frequency response range, mechanical moving parts not easily damaged, light weight and good dynamic response than magnetoelectric velocity transducers.Features:Equipped with precision integrator circuitUsing the piezoelectric effect of piezoelectric materialsWide frequency response, suitable for small vibration velocity measurementGood reliability, suitable for random direction as vertical and horizontalSpecifications:ModelCV-YD-002CV-YD-004CV-YD-005CV-YD-010 CV-YD-021Sensitivity (20±5℃)400mV/mm/s0.64mA/mm/s150mV/mm/s10.8mA/mm/s4mV/mm/sMeasurement Range10-25mm/s0～25.4mm/s0-20mm/s0-20mm/s±1000 mm/sFrequency Range4～2000Hz4～2,000Hz4～2000Hz10～1,000Hz4～4,000HzOperating Temp.
