PCB® and IMI Sensors Launch New High-Temperature Charge Accelerometer with UHT-12™ Element

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.

The new model features a well-balanced, differential output that is isolated from case ground to reduce electrical noise found near aeroplane 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, which are ideal for gas turbine engine research and monitoring.
