	Type; PMP131B Pyongyang membrane type.

working principle	The pressure sensor based on the principle of silicon piezoresistive is a precision silicon electric sensor made by vacuum diffusing semiconductors on a silicon substrate
	Resistance strain bridge. It is separated from the measured medium by a layer of stainless steel corrugated sheet, and the strain bridge is connected to the stainless steel corrugated sheet
	There is an intermediate fluid filled between them - silicone oil. When pressure P acts on the corrugated sheet and is transmitted to the strain bridge through the intermediate fluid, the bridge
	The change in resistance causes the bridge to lose balance and output a series of voltage signals proportional to the pressure P. Through signal amplification, the circuit
	Convert to standard electronic signal output.
