PMP-PMP317 Compact Diffuser Silicon Pressure Transmitter Rod shaped Compact Ceramic Pressure Resistive Liquid Gas Clever Diffuser is generally used to measure the pressure of gases, products, or vapors, and then convert the measured signal into a 4-20mA current signal or 0-5V voltage signal for output. The main categories include capacitive smart diffusion silicon, smart diffusion silicon, strain smart diffusion silicon, and 17 small diffusion silicon. The principle is that the medium acts directly on the sensitive diaphragm of the smart diffusion silicon in the front end of the gas chamber, and the Wheatstone bridge composed of resistors distributed on the sensitive diaphragm of the gas chamber uses the piezoresistive effect to achieve the conversion of pressure to electrical signals. The millivolt signal generated by the sensor sensitive element at the front end of the smart diffuser is amplified into an industrial standard signal through electronic circuits.
