PCB® has announced new crystal technology being used in high temperature applications called UHT-12™ operating to 650°C. Accelerometers with UHT-12™ make measurements with better accuracy and lower noise over large temperature profiles.

This development solves the gas turbine manufacturers’ problems with ceramic based sensors known as pyroelectric noise, the material can operate in shear mode, isolating the accelerometer from thermal influences and base strain errors.”

UHT-12™ technology allows accelerometers to be insensitive to temperature variations. Ideal for applications such as test and monitoring vibration of gas turbine engines, rocket motors and thruster assemblies, turbocharger and exhaust system test and engine balancing. 

The UHT-12™ family comprises ICP® and charge accelerometers including models 320C52, 357D90, 357D91, EX611 and series 339. The new UHT-12™ crystal technology has also been adapted to pressure sensor series 115 and 176.
