Miniature Dynamic Pressure Sensors from PCB Piezotronics
January 23, 2007
PCB Piezotronics has introduced Series 105, a new family of ICP miniature dynamic pressure sensors, suited for monitoring dynamic combustion pressure in diesel and natural gas powered engines and other reciprocating equipment.
Proper monitoring 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.
Additionally, Series 105 features a 4.2 mm diaphragm and M5 thread, and can be mounted internal to the engine.
With no moving parts and solid-state construction, the pressure sensors offer optimal durability.
Frequency response may be tailored for use on low or high-speed engines. Series 105 pressure sensors have ranges to 3,600 psi (250 bar) and a max pressure of 4,000 psi (300 bar). Suitable for high temperatures, the sensors are packaged in stainless steel housings, with rugged cables, integral charge amplifiers, and connectors. Intrinsically safe versions are also available for explosive gas atmospheres.
