High Temperature Piezoelectric Accelerometers on-line catalog

The category of High Temperature Piezoelectric Accelerometers is typically reserved for units that are capable of achieving operating temperatures from 500 °F (260 °C) to 1200 °F (648 °C). These sensors utilize customized ceramic or piezo-crystalline materials, as well as specialized manufacturing processes, to ensure survivability in the harshness of extreme temperature. Since the temperature limits achievable with these devices exceeds the capability of the circuitry used for ICP^® (IEPE) types, these extreme temperature accelerometers all operate in the charge output mode. Another virtue of most of the models in this category is their ability to withstand exposure to radiation. Such "Rad Hard" units have been deployed in nuclear power generating facilities.

Two varieties of output signal formats are offered - single ended and differential. Single ended refers to a two-conductor system comprised of an output signal and ground. The differential mode utilizes a common ground with both a positive and negative polarity signal, which when combined with the use of appropriate signal conditioning, offers common mode noise rejection for improved signal fidelity.
