Columbia Series 8410 Piezoelectric Accelerometers are completely self-contained vibration measuring systems having a built-in amplifier within the housing. They are designed for the measurement of low level, broadband frequency vibrations.
The Series 8410 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 20 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.
