MicroSensor MDM490 Differential Pressure Transmitter Low Range for Petroleum Chemical Industry

0~30bar Low Range Accurate 4~20mADC 1~5VDC Water Liquids Oil Differential Pressure TransmitterDescriptionMDM490 uses piezoresistive sensor as the sensing element, silicon oil is filled between the die and two diaphragms. When the measured differential pressure is added on the two diaphragms, the pressure could be transferred onto the die through silicon oil. The sensor die connects with an amplifier circuit through wires, uses the semiconductor's piezoresistive effect to transform the differential pressure signal into the electric signal. Since the signal output of the Wheatstone bridge on the die has a good linear relationship with the differential pressure, the differential pressure can be accurately measured.Features• Intrinsic safety product, Ex ia IIC T6 Ga• Laser welding, full-sealed structure• Temperature compensation and aging, stable and reliable performance• Zero and span adjustable outside• CE, RoHS and CCS approved Application• Petroleum industry• Chemical industry• Electricity industry• HydrologyCertificates• CE;• RoHS;• ISO SpecificationOrder GuideMDM490Piezoresistive Differential Pressure Transmitter  CodePressure range: kPa or MPa X[0~X]kPa or MPaCodePressure rangekPaoverpressurekPaCodePressureRange   MPaOverpressure MPa+-+-0A0~357035090~0.71.40.7020~7015070100~1.02.01.0030~100200100120~2.04.01.007 0~200400200130~3.57.01.0080~350700350       CodeOutput signalE4~20mADCF1~5VDCJ0~5VDCQ0~10mADCU0~20mADCV0~10VDC    CodeConstruction material DiaphragmPressure portHousing 22SS 316LSSSS 24SS 316LSS 316LSS 316L   CodeOthers C4G1/4 female B1Plug connection B2Cable connection    Default length: 1.5m M331/2LCD digital indicator(only 4~20mADC) M431/2LED digital indicator (only 4~20mADC) iIntrinsic safe version ExiaIICT6(>35kPa) /ExiaIIBT6Ga(
