Sensors measure dynamic pressure oscillations
PCB Piezotronics is introducing a series of dynamic pressure sensors suitable 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 well suited to detecting and measuring dynamic pressure phenomena. With very fast response times, these sensors accurately measure fast transient pressures, such as surges, spikes, pulsations and noise. With no moving parts and solid-state construction, their durability is claimed to be unsurpassed by any other type of pressure sensor. The Series 171 pressure sensor has sensitivities to 1200pC/psi (174pC/kPa), a pressure range of 10psi (70kPa) and a maximum pressure of 600psi (4140kPa). They are suitable for high temperatures of up to +500degF (+260degC) and are packaged in a case-isolated housing with rugged two-pin MIL connectors.
