PMC131 pressure transmitter

Product Features	The PMC131 pressure transmitter adopts imported ceramic sensors or imported silicon piezoresistive sensors. PMC131 ceramic sensor is composed of
	96% or 99% alumina ceramic film forms a flat capacitor structure. The medium pressure of the sensor directly acts on the ceramic
	The sensor diaphragm causes displacement of the measuring diaphragm. Normal pressure causes the measuring diaphragm to deviate by 0.025mm. Under overpressure conditions
	Only offset the measuring membrane by 0.1mm. At this point, the measuring membrane is attached to the ceramic bracket to avoid damage to the sensor
	The capacitance generated by the displacement of the measuring film is detected by the electronic components directly connected to it, amplified and converted into a standard signal
	Output; PMC13A and PMC13B silicon piezoresistive sensors are precision sensors made by vacuum diffusing semiconductors on a silicon substrate
	Dense resistance strain bridge. It is separated from the detected medium by a layer of stainless steel corrugated sheet, and is transmitted through an intermediate liquid
	To a strain bridge, the change in bridge resistance causes the bridge to lose balance and output a series of voltage signals proportional to the pressure P. pass
	Signal amplification, circuit conversion standard electronic signal output.
