Diesel & Gas Engine Combustion Pressure Sensors

March 22, 2007, Depew, NY, USA – PCB Piezotronics, Inc. (PCB®) has introduced a new series of dynamic pressure sensors, ideal for monitoring dynamic combustion pressure in diesel and natural gas powered engines and other reciprocating equipment. Proper monitoring of engines and machinery using these sensors allows for extended maintenance intervals, improved fuel efficiency, and lower NOx emissions. Sensors feature piezoelectric sensing elements with very fast response times, and are best suited for continuous monitoring or periodic walk-around cylinder balancing. Intrinsically safe versions are available for explosive gas atmospheres.

With no moving parts and solid-state construction, the durability of Series 175 is unsurpassed by any other type of pressure sensor. Frequency response may be adjusted for use during engine load changes on low or high-speed engines. These sensors have measurement ranges up to 3,600 psi (250 bar) and a maximum pressure of up to 4,000 psi (300 bar). They are well-suited for use in high temperatures up to +570 °F (+300 °C), and are packaged in stainless steel housings with rugged cables and connectors. Series 175 features a robust M14 thread, and may be mounted to existing engine pressure indicator valves.
