PCB Piezotronics Introduces Ultra-High Temperature Pressure Sensor

Ideal for Combustion Dynamics and Thermoacoustic Measurements

Model 176A33 Allows for Continuous Operation at 1400 °F (760 °C) without Need for Water Cooling

October 20, 2023, Depew, NY – PCB Piezotronics, Inc. today announced the release of a new ultra-high temperature pressure sensor for combustion testing and thermoacoustic pressure measurements with a unique design element that eliminates the need for water cooling. The new model 176A33 pressure sensor features a temperature rating of 1400 °F (760 °C).

This new pressure sensor measures combustion dynamics as well as gas turbine measurements, thermoacoustic measurements, rocket motor combustion instability or any high temperature, dynamic gas pressure measurement. In these demanding test environments, PCB’s UHT-12 sensing element uses a crystal designed for more accurate, lower noise measurements during large temperature variations.

The 176A33 single ended pressure sensor has a high sensitivity of 6 pC/psi, a measurement range of 3000 psi (207 bar), and a maximum pressure rating of 5,200 psi (359 bar) with a 3 foot (1 meter) hardline cable terminating in a double isolated 10-32 connector.

“This new design eliminates the need for water cooling up to 1400 °F,” said Bob Metz, director of sales and marketing for aerospace and defense division at PCB Piezotronics. “This makes the new 176A33 pressure sensor an excellent choice for research facilities that perform thermodynamic and acoustic measurements during combustion research.”
