Dynamic Pressure Sensor for Gasoline or Diesel Engine Combustion Monitoring

June 27, 2007, Depew, NY, USA – PCB Piezotronics (PCB®) has introduced a new dynamic pressure sensor, ideal for measuring dynamic combustion pressure in gasoline or diesel engines. The high temperature (to +600 °F/+315 °C) piezoelectric charge output sensor, structured with naturally stable quartz sensing elements, is well-suited to measure rapidly-changing pressure fluctuations over a wide amplitude and frequency range.

The un-cooled design measures pressure with low thermal shock error, and ground isolation avoids electrical interference from electronic ignition systems, making the sensor equally well-suited for research and development or monitoring applications. A solid-state construction, hermetically-sealed housing, and laser-welded flush diaphragm help ensure durability in harsh engine testing environments.

The Model 175A01 pressure sensor is available with a dynamic range to 4000 psi (275 bar), and sensitivity of 1.5 pC/psi (21 pC/bar). Alternate models and mounting adaptors are available for various engine types. For detailed specifications, drawings, or additional information, please visit www.pcb.com
