Accelerometer delivers high performance for
seismic and low frequency measurements
The Endevco model 86 is a piezoelectric accelerometer with integral electronics, designed specifically for measuring ultra low level, seismic events and low frequency vibration on structures and objects. It is ideal for floor isolation testing, photolithography applications, and high accuracy manufacturing environments.
The unit is hermetically sealed against environmental contamination and features a 10 V/g sensitivity, state-of-the-art signal-to-noise ratio, sensitivity of 10 V/g, near-dc frequency response that is flat to 0/01 Hz and temperature range of -23 to +212 degrees F. Dimensions are 2.55 inches in diameter by 2.18 inches in height (excluding pin connector).
The model 86 incorporates an advanced ultra low noise hybrid circuit operating in a 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 low-noise cable assembly is provided as a standard accessory.
