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.
