The Vibration Division of PCB Piezotronics, Inc., (PCB®) has introduced a new line of high temperature piezoelectric charge output accelerometers for vibration studies on aircraft engines, and other high temperature measurement environments.

These high temperature sensors are designed for stable sensitivities of 4 pC/g in temperature ranges of -65 to +900º F (-54 to +482º C). Their piezoceramic sensing element is housed in a rugged, all-welded, hermetically sealed Inconel® housing. Accelerometers connect to laboratory-style charge amplifiers or in-line charge converters, which condition the output signal for recording or analysis. They feature a measurement range of ±500 g, 3,000 g shock limit and a 10-32 coaxial electrical connector.
