New 650°C operating accelerometer eliminates noise spikes

17 April 2015

PCB Piezotronics has introduced new crystal technology for high temperature applications called Ultra High Temperature 650°C (1200°F) or UHT-12.

Accelerometers designed with UHT-12 make measurements with better accuracy and lower noise over large temperature profiles.

The development solves the gas turbine manufacturers’ problems with ceramic based sensors - namely, pyroelectric noise. The material also has the ability to 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. This is ideal for applications such as test and monitoring vibration of gas turbine engines (both in-flight and in test cells), rocket motors and thruster assemblies, turbocharger and exhaust system test and engine balancing. 

The family comprises ICP and charge output accelerometers, including models 320C52, 357D90, 357D91, EX611 and series 339. The new high temperature crystal technology has also been adapted to pressure sensor series 115 and 176.

UHT-12 technical advantages include elimination of pyroelectric noise spikes up to 650°C, consistent sensitivity over a wider temperature range and isolation of the crystal from base strain and transverse measurement errors.
