Flat membrane pressure sensor is a common industrial practice of a pressure sensor, which is widely used in a variety of industrial self-control environment, involving petroleum pipelines, water conservancy and hydropower, railroad transportation, intelligent buildings, production automation, aerospace, military, petrochemical, oil wells, electric power, ship, machine tools, pipeline air supply, boiler negative pressure and many other industries.
Working Principle.
The working principle of the flat membrane pressure sensor is the medium pressure directly on the sensor's diaphragm, so that the diaphragm produces with the medium pressure is proportional to the micro-displacement, so that the sensor's resistance to change, and with the electronic circuit to detect this change, and convert the output of a standard signal corresponding to the pressure.
