NS-P424 Compact Diffuse Silicon Pressure Transmitter Rod shaped Compact Ceramic Pressure Resistive Liquid Gas Pressure Transmission Diffuse Silicon Pressure Gauge is generally used to measure the pressure of gas, pressure body or steam, and then convert the measured signal into a 4-20mA current signal or 0-5V voltage signal for output. The main classifications include capacitive silicon pressure variation, volumetric silicon pressure variation, strain based silicon pressure variation, and flexible diffusion silicon pressure variation. The principle is that the medium dispersed silicon directly acts on the sensitive diaphragm of the pressure sensor at the front end of the dispersed silicon pressure transformer. The Wheatstone bridge composed of resistors distributed on the sensitive diaphragm of the pressure sensor uses the piezoresistive effect to achieve a conversion process from pressure to electrical signal. The millivolt signal generated by the sensor sensitive element at the front end of the dispersed silicon pressure transformer is amplified into an industrial standard signal through electronic circuits.
