Background
A pressure transmitter is a device that converts pressure into a pneumatic signal or an electric signal for control and remote transmission. The pressure sensor can convert physical pressure parameters of gas, liquid and the like sensed by the pressure element sensor into standard electric signals (such as 4-20 mADC and the like) so as to supply secondary instruments such as an indication alarm instrument, a recorder, a regulator and the like for measurement, indication and process regulation.
As a result of past long overpressures, pressure sensors in pressure transmitters experience a variety of physical changes before the end of the life of the transmitter, including repeated deformation damage to metal components due to the overpressure. These physical changes can cause the accuracy of the sensor output to deteriorate. The existing pressure sensor mounting structure is inconvenient to disassemble and assemble and cannot adjust the position of the pressure sensor.
