A pressure sensor converts changes in pressure of a gas or a liquid into an electrical signal by means of a pressure sensing device and generates an analog output proportional to the pressure or a switching output that operates at a particular pressure level. All Panasonic pressure sensors incorporate semiconductor transducers, which offer long life and high reliability, as the sensing devices.
A stainless diaphragm is used as the transducer. Besides air pressure, it can be used to measure the pressure of gases or liquids which do not corrode stainless steel (SUS 302 and SUS 304) port.
A diffused semiconductor is used as the transducer. It can be used to measure air pressure.
