The fuel pressure sensor is composed of a printed circuit board, a sensor element, a gasket and a housing. There is a pressure chamber in which there is a diaphragm with an relief valve, a vacuum chamber on the back of the diaphragm, and a spring in the chamber. So what is the function and working principle of the fuel pressure sensor?
The function of the fuel pressure sensor is to measure the fuel pressure in the fuel pipe after the fuel pump, and then convert the oil pressure into an electrical signal, which is transmitted to the display instrument or signal acquisition device.
The working principle of the oil pressure sensor is that the pressure directly acts on the diaphragm of the sensor, so that the diaphragm generates a small displacement proportional to the medium pressure, so that the resistance of the sensor changes. An electronic circuit detects this change and then converts and outputs a standard signal corresponding to that pressure.
Application: Widely used in various industrial automatic control environment, involving oil pipelines, water conservancy and hydropower, railway transportation, intelligent buildings, production automatic control, aerospace, military, petrochemical, oil Wells, electric power, ships, machine tools, pipeline gas supply, boiler negative pressure and many other industries. Easy to install, long service life.
