working principle	·Ceramic capacitive dry sensor
	A flat capacitor structure is composed of 96% or 99% alumina ceramic film. The medium pressure of the sensor directly acts on the ceramic transmission
	Sensor membrane causes displacement of the measuring membrane. Normal pressure causes a displacement of 0.025mm in the measuring diaphragm. Overpressure only causes
	Measure the displacement of the diaphragm by 0.1mm. At this point, the capacitance generated by the displacement of the diaphragm is detected by an electronic component directly connected to it,
	Amplify and convert to standard signal output.
	·Metal diffusion silicon piezoresistive sensor
	A pressure sensor is a standard silicon resistance strain bridge made by vacuum diffusing semiconductors on a silicon substrate. It is directly connected to the tested medium
	There is a layer of stainless steel corrugated sheet at the junction, and an intermediate fluid - silicone oil - is filled between the strain bridge and the stainless steel corrugated sheet. When the pressure P
	Acting on the corrugated sheet and transmitted to the strain bridge through the intermediate fluid, the change in bridge resistance causes the bridge to lose balance and output a series of outputs that are proportional to the pressure
	A proportional voltage signal. By amplifying the signal, the circuit is converted into a 4-20mA output.
