1 MM480 iezoresistive ressure Transmitter Features Wider pressure range; Full stainless steel construction; optional pressure port; flush diaphragm type, sanitation type and anti-corrosive type are available; protection I65; Optional output signal; local calibration and displayable; Reversed-polarity, transient current & voltage protection, which conform to EMI standard; Intrinsic safe ex-proof version conforming to GB Exia CT6 Regulation; Ex-proof Certificate is issued; EXD product conforming to GB Exd CT6 Regulation; EXD Certificate is issued; Ship-use product conforming to CCS Rules of Classification of Sea-going Steel Ships 2006; Ship-use Certificate is issued; CE and RoHS Certificates; National patent, patent No.: ZL Introduction MM480 transmitter uses piezoresistive OEM pressure sensor with isolated stainless steel diaphragm as signal sensing element, through automatic testing, laser trimming compensating zero and sensitivity in wider temperature range; the amplifier circuit is in stainless steel housing, transforming sensor signal into standard output signal. Through strict component making, semi-finished product and all-finished product testing and aging, the transmitter is stable and reliable, having excellent flexibility, sensitivity and diversity. The product is widely used for pressure measure and control of petroleum, chemi-industry, metallurgy, power station and hydrology, etc. Specification ressure range: Ma Overpressure: 1.5 times FS or 110Mamin. value is valid ressure type: gauge, absolute or sealed gauge Accuracy: 0.25%FStyp. 0.5%FSmax.
