The Model 8405 Piezoelectric Accelerometer is a completely self-contained vibration measuring system having a built-in amplifier within the housing. It is designed for the measurement of low level, broadband frequency vibrations.
The Model 8405 incorporates a hybrid electronic assembly within a rugged, welded stainless steel body to enhance its operation in humid and dirty environments. 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.
