Designed for gas turbine applications and other 900°F (482°C) environments.
PCB Piezotronics announced the release of Model 357A100, a new high temperature differential charge accelerometer with a UHT-12™ sensing element. This accelerometer is for use during gas turbine engine research and testing and has industry standard 3-hole mount. This new model features a well-balanced, differential output that is isolated from case ground to reduce electrical noise found near airplane and helicopter gas turbine engines. Its charge output is self-generating and does not require an external power source.
The new UHT-12™ crystal technology features: Absence of pyroelectric noise spikes up to 900 °F (482 °C). Sensitivity that remains more consistent over a wide temperature change. Shear mode crystals isolated from base strain and transverse measurement errors. No depletion of oxygen at high temperatures, eliminating the need for a vent or window in the housing. PCB® offers a family of ultra high temperature accelerometers and pressure sensors for aerospace propulsion. These sensors are ideal for gas turbine engine research and monitoring.
