MBC-1 Compact Diffuse Silicon Pressure Transmitter Rod shaped Compact Ceramic Pressure Resistive Liquid Gas Pressure Sensor Pressure transmitter is generally used to measure the pressure of gases, liquids, or vapors, and then convert the measured signal into a 4-20mA current signal or 0-5V voltage signal output. The main categories include capacitive pressure transmitters, ceramic pressure transmitters, strain gauges, and diffusion silicon pressure transmitters. The principle is that the medium pressure directly acts on the sensitive diaphragm of the front-end sensor of the pressure transmitter, and the Wheatstone bridge composed of resistors distributed on the sensitive diaphragm of the sensor uses the piezoresistive effect to achieve the conversion of pressure to electrical signals. The millivolt signal generated by the sensitive element of the front-end sensor of the pressure transmitter is amplified into an industrial standard signal through electronic circuits.
