The Models 8011 and 8012 Piezoelectric Accelerometers are designed for the measurement of high frequency, moderate to high-level shock and vibration. They incorporate a hybrid electronic assembly within a rugged, welded, double-wall stainless steel body to enhance operation in humid and dirty environments.
The sensor's double-wall, electrically isolated construction provides additional isolation from metallic structures, which aids in acquiring accurate, wideband shock and vibration data uncorrupted by electrical ground loop currents. The sensor module is bonded into the outer stainless steel body with a high temperature, glass-filled polymer insulator. 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 500 feet of shielded cable
