Above this temperature, many of thedesign features and materials used in high temperatureaccelerometers change considerably. For 288 ºC to 650 ºCoperating environments, PCB ® offers a range of both singleended output (measurement output as a signal and ground)and differential output (measurement output as a plus andminus signal) sensors. The former tend to be smaller andmore suitable for short term testing needs, while the latterare more appropriate for long term monitoring applications.Obviously, the environments in which these sensors operateare challenging. In fact, in some of the highest temperatureoperating environments, the operating sensor measuresvibration signatures while glowing red hot. These sensorsare complemented by both lab grade and in-line chargeamplifier systems. This differential charge amplifier issuitable for interfacing to any of PCB’s differential chargeoutput accelerometers.Accessories & Cables: Pages 146 - 159
