Piezoelectric Accelerometers for Vibration & Shock Measurement

Models 962 and 962A Piezoelectric Accelerometers from Columbia Research Laboratories are specifically developed for the measurement of high frequency, intermediate to high-level shock, and vibration.

They involve a hybrid electronic assembly inside a rough, welded, double-wall stainless steel body to improve functioning in dirty and humid surroundings.

The double-wall and electrically-isolated construction of the sensor offers extra isolation from metallic structures, which helps in obtaining precise, wideband shockand vibration data unspoiled by electrical ground loop currents.

The sensor module has been bonded into the outer stainless-steel body with the help of a high temperature and glass-filled polymer insulator. Impedance output that is 100 ohms or less enables operation directly into standard readout equipment without auxiliary signal conditioning and has the potential to drive up to 500 ft of shielded cable.

Users can consult the factory for the sensor’s customized versions.
