PTX-PTX7535 Compact Diffusion Silicon Pressure Transmitter Rod shaped Compact Ceramic Pressure Resistive Liquid Gas Compact Expander is generally used to measure the pressure of gases, bodies, 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 small diffusion, delicate small diffusion, strain type small diffusion, and 535 small diffusion. The principle is that the medium is small and directly acts on the sensitive diaphragm of the small diffusion front-end liquid device. The Wheatstone bridge composed of resistors distributed on the sensitive diaphragm of the liquid device 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 small diffusion front-end is amplified into an industrial standard signal through electronic circuits.
