Dynamic Pressure Sensors for Turbine Engine Monitoring

February 8, 2007, Depew, NY, USA – PCB Piezotronics, Inc. (PCB®), introduces a series of dynamic pressure sensors, ideal for monitoring dynamic pressure oscillations in turbine engines. Variations in Natural Gas can lead to increased dynamic pressure oscillations in the turbine combustors, resulting in inefficiencies, increased NOx emissions and damaging combustion instabilities. Additionally, these sensors may also be used to detect high-intensity acoustics, pulsations, and pressure fluctuations in pumps, furnaces, and pipes.

Piezoelectric pressure sensors are best suited for detecting and measuring dynamic pressure phenomena. With very fast response times, these sensors accurately measure fast transient pressures, such as surges, spike, pulsations and noise. With no moving parts and solid-state construction, their durability is unsurpassed by any other type of pressure sensor. The Series 171 pressure sensor has sensitivities to 1200 pC/psi (174 pC/kPa), pressure range of 10 psi (70 kPa); and a maximum pressure of 600 psi (4140 kPa). They are suited for high temperatures up to +500 °F (+260 °C) and are packaged in a case isolated housing with rugged, 2-pin MIL connectors.
