Piezoelectric Accelerometer for Cryogenic Services in Cold Temperatures

The Model 876 Piezoelectric Accelerometer from Columbia Research Laboratories has been designed for vibration measurement or tracking applications that need operation at extremely cold temperatures.

The accelerometer is ideal for event and vibration tracking of valves and pumps applied in the cryogenic service.

The shear plate construction offers utmost mechanical isolation from thermal shock transients and strain-induced inputs. The electrically separated and double case construction provides electrostatic shielding as well as decreasing power line frequency noise due to multi-point grounding. The accelerometer equips a 10 to 32 top connector.

Users can consult the factory for tailored versions of this sensor.
