378 HT 2XP

  • Vibration & Shock
  • Extreme High Temperature (+750 Deg F)
  • Electrically Isolated
  • Hermetically Sealed
  • Integral SS Cable

The Series 378-HTXP Piezoelectric Accelerometers are precision manufactured sensors designed for use in extremely severe and volatile environments to measure shock and vibration of structures subject to very high temperatures. 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, internally isolated electrically with 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 -28 removable stud for mounting.

Consult the factory for customized versions of these sensors.
