High sensitivity piezoelectric accelerometer with integrated electronics
500 mV/g | 8405 Columbia Research Laboratories

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 incorporated a hybrid electronic assembly within a rugged, stainless steel body to enhance operation in humid an dirty environments. Signal ground is connected to the outer case of the unit. Low impedance 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.
