- The VSM797S is a hermetically sealed piezoelectric accelerometer designed to measure absolute vibration in harsh industrial environments. It incorporates a lowpass filter within the conditioning circuit to attenuate the sensor’s mechanical resonance as well as the associated distortion and overload. The sensor features a low noise and temperature compensated design to ensure accurate results throughout the entire operating temperature range.
