PMC73/PMC73F pressure transmitter

Product Features	Adopting a diffused silicon sensor with 0.075% high precision, 20:1 wide range ratio, high stability and reliability, and equipped with HART communication function,
	It has intrinsic safety, explosion-proof type, optional isolation membrane structure, multiple process connection standards, and is suitable for micro pressure, high temperature and high pressure
	Pressure measurement under low temperature and corrosive conditions.

working principle	Using semiconductor planar process technology to fabricate resistance bridges on silicon wafers. The medium pressure causes the metal diaphragm to shift,
	Transfer pressure to the resistance bridge circuit through an intermediary fluid. The resistance bridge circuit will output a line with the pressure signal when subjected to pressure
	The pressure signals of sexual relationships are further processed by electronic components and converted into standard signal outputs.
