PCB Piezotronics’ Model 175A01 dynamic pressure sensor is suitable for measuring dynamic combustion pressure in diesel engines. The piezoelectric charge output sensor operates up to 600°F (315°C) and is structured with stable quartz sensing elements to measure rapidly changing pressure fluctuations over various amplitude and frequency ranges. The un-cooled design measures pressure with low thermal shock error, and ground isolation avoids electrical interference from electronic ignition systems. A solid-state construction, hermetically sealed housing, and laser-welded flush diaphragm are designed for durability in harsh engine testing environments, making the sensor suitable for research and development or monitoring applications. Model 175A01 is available with a dynamic range to 4000 psi (275 bar), and alternate models and mounting adaptors are available.
