Embodiment 1
[0017] The measured pressure enters the inside of the pressure sensor 4 through the medium inlet 1, and the pressure directly acts on the concave diaphragm of the sensor 4, which produces a micro-displacement proportional to the water pressure, changes the resistance value of the bridge arm, and generates a differential voltage signal , that is, based on the piezoresistive effect, the conversion of the pressure signal to the electrical signal is realized, and then the change of the resistance value is detected by the signal modulation circuit, and the standard analog signal corresponding to the water pressure is converted and output. When the membrane sensor is broken, the outlet is blocked to avoid medium leakage and backflow after the water pressure exceeds the capacity of the concave membrane. The performance and service life of the pressure sensor 4 are affected. The transmission line is used for power supply and voltage signal output of the pressure sensor 4 .
