Extreme Sensors for Extreme Temperatures

Vibration testing of aircraft gas turbine engines, industrial turbines, rocket propulsion systems, and exhaust systems requires accelerometers that are designed to withstand very high temperature environments. These sensors are also required for automotive exhaust monitoring, engine system testing, catalytic converter testing, and brake testing.

UHT-12™ is a new crystal designed for more accurate, lower noise measurements during large temperature variations and trusted in the most demanding test environments. PCB® sensors made with UHT-12™ technology have an improved data quality compared to ceramic crystal designs.

The main technical advantages include:

  • Absence of pyroelectric noise spikes up to 1400 ºF (760 ºC)
  • Sensitivity that remains more consistent over a wide temperature change
  • Shear mode crystals isolated from base strain & transverse measurement errors
  • Proprietary crystal technology comes sealed in a hermetic package and has proven reliable performance in hundreds of gas turbine installations for research and monitoring

The UHT-12™ family consists of accelerometer Models 320C53, 320C52, 357E90, 357E91, 357E92, 357E93, 357A100, EX611A00, EX600B13, 339A30, 339A31, 339A32 and has been adapted to pressure sensor Series 115 and 176.
