Pressure sensor is a device that converts pressure into current or voltage, which can be used to measure the pressure and displacement of an object.
(1) metal elastic pressure sensor. The most commonly used elastic measuring elements are spring, spring tube, bellows and elastic diaphragm. These pressure measuring elements first convert pressure change into displacement change, and then convert displacement change into electric quantity which is easy to be detected, processed and displayed by magnetoelectricity or other electrical methods.
1) resistance differential pressure sensor.
2) Capacitive differential pressure sensor.
3) Hall pressure sensor.
