The Model 8412 Piezoelectric Accelerometer is a completely self-contained vibration measuring system having a built-in amplifier within the housing and offers wide frequency response. It is designed for the measurement of medium level, broadband frequency vibrations.

The Model 8412 incorporates a hybrid electronic assembly within a rugged, stainless steel body to enhance its operation in humid and dirty environments. Internal electrical damping limits the resonant Q to less than 30 dB. Signal ground is connected to the outer case of the unit. Low impedance output of 100 ohms or less allows operation directly into standard readout equipment without auxiliary signal conditioning, and is capable of driving up to 1,000 feet of shielded cable.
