Accelerometer technology eliminates noise spikes up to 650°C

UHT-12 technology allows accelerometers to be unaffected by temperature variations, which is particularly useful in the testing and monitoring of vibration in gas turbine engines, rocket motors and thruster assemblies, as well as the testing and engine balancing of turbocharger and exhaust systems.

The UHT-12 family consists of ICP and charge output accelerometers, including models 320C52, 357D90, 357D91, EX611 and series 339. The high temperature crystal technology has also been adapted for the pressure sensor series 115 and 176.

"This development solves the gas turbine manufacturers’ problems with ceramic based sensors known as pyroelectric noise," said Bob Metz, Director, Aerospace & Defense, PCB. "The material also has the ability to operate in shear mode, isolating the accelerometer from thermal influences and base strain errors."
