Piezoelectric accelerometers measure shock, vibration in high-temp environments

The Series 378-HT-XP piezoelectric accelerometers from Columbia Research Laboratories Inc. are precision manufactured sensors designed to measure shock and vibration of structures subject to very high temperatures.

They are effective for use in nuclear facilities and other severe and volatile environments. The unique design of the piezoelectric seismic system ensures that the units have no discernible spurious response to mounting torque, body strains, cable vibration, cable whip, pressure variations, and most heat transients. The units are hermetically sealed and internally isolated electrically. They have an extremely rugged housing for prolonged use in adverse industrial environments of shock, vibration, temperature, humidity, and excessive oil.

The Series 378-HT-XP accelerometers are equipped with an integral stainless steel sheathed cable and supplied with a ¼-28 removable stud for mounting. Customized versions are available through consultation with the factory.
