Series 378-HT-XP piezoelectric accelerometers from Columbia Research Laboratories Inc., Woodlyn, PA, are designed to measure shock and vibration of structures subjected to temperatures from –73°C to 398°C. Sensors are hermetically sealed and internally isolated electrically, have a SS case, weigh 6.8 oz., and have a vibration limit of 500 g max. (sine) and 1000 g max. shock. The devices' design ensures that they have no discernable spurious response to mounting torque, body strains, cable vibration, cable whip, pressure variations, and most heat transients. Applications include use in nuclear facilities and other severe and volatile environments.
