Product Details
Internal ICP piezoelectric accelerometer is newly developed electromechanical measuring transducer. It utilizes positive piezoelectric effect to produce high impedance charge, low impedance voltage signal will be output after transform in internal integrating circuit, and enter the readout, indication and record instrument. It features small size, big stiffness, wide frequency response, high sensitivity and easy use. It’s used widely in vibration and shock field.
Piezoelectric transducer of internal circuit seals impedance transform circuit in the stiff body of transducer, other than easy use, simple operation, it features:
Low impedance (<100O) ultra long cable in bad environment is allowed.
Fixed voltage sensitivity which has nothing to do with the length of cable and capacitance.
As binary system, it can be matched with cheap universal coaxial cable and double line cable.
Low impedance voltage output can be matched with universal readout/ readout/ process instrument.
Only low cost constant current power is needed, and expensive charge amplifier can be saved.
The maintenance demands of the measuring system can be decreased.
Highlight:
The main sensing element Piezoelectric Ceramics are made by ourselves with good stability and consistency.
