Overview
The domestically produced resistance strain type aviation plug diaphragm pressure sensor uses the principle of resistance strain to attach high-precision foil strain gauges to elastic beams. When the measured external force acts on the elastic beam through the pressure head, the elastic beam undergoes bending deformation, and the relative deformation of the beam is proportional to the external load. By applying an excitation voltage, the force on the sensor is converted into the corresponding electromotive force, thus achieving the measurement purpose. There are four screw holes on the bottom of the $r $n sensor for fixing and installing the sensor.

Domestic resistance strain gauge aviation plug diaphragm pressure sensorProduct Overview:
Using the principle of resistance strain, a high-precision foil strain gauge is attached to an elastic beam. When the measured external force is applied to the elastic beam through a pressure head, the elastic beam undergoes bending deformation, and the relative deformation of the beam is proportional to the external load. By applying an excitation voltage, the force on the sensor is converted into the corresponding electromotive force, thus achieving the measurement purpose.
There are four screw holes on the bottom of the sensor for fixing and installing the sensor.
