Low noise piezoelectric accelerometer
1 / 10 V/g | Model 87 Meggitt Sensing Systems - Endevco

Endevco® Model 87 is an ultra low-noise piezoelectric (IEPE-type) accelerometer with integral electronics, designed specifically for measuring ultra-low level, seismic events and low-frequency vibration on structures and objects. The unit is hermetically sealed, and offers a 1 V/g or 10 V/g sensitivity, low signal-to-noise ratio, and near-DC frequency response.

Model 87 incorporates an advanced ultra-low noise hybrid circuit, which operates in constant current mode. A simple two-wire system transmits its low-impedance voltage output and the required power. Signal ground is isolated from the outer case and mounting surface to prevent ground loops. A specially designed cable assembly is available as an optional accessory.
