Dynamic pressure measurements, such as turbulence, blast, ballistics, and engine combustion, often require sensors specifically designed to detect and measure fast, transient pressures, such as surges, spike, pulsations, and noise. In addition, the sensors need to withstand rugged environments. Turbine combustors, for example, benefit from such sensors since they are susceptible to dynamic pressure oscillations from variations in natural gas. These oscillations cause inefficiencies, increased NOx emissions, and damaging combustion instabilities. The Series 171 pressure sensor from PCB Piezotronics 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). It is suited for temperatures to +500° F (+260° C) and is packaged in a case isolated housing with rugged, 2-pin MIL connectors. The sensors also detect high-intensity acoustics, pulsations, and pressure fluctuations in pumps, furnaces, and pipes.
The Series 171 dynamic pressure sensor is ideal for monitoring combustion in turbines.
