EJA438W Diaphragm SeaLED GaugePressure Transmitters
EJA438W Diaphragm Sealed GaugePressure TransmittersFeatures :Diaphragm seal is used to prevent process medium from entering directly into the pressure-sensing assembly of thepressure transmitter. It is connected to the transmitter using capillary filled with fill fluid.Models EJA438W and EJA438N Diaphragm Sealed Gauge Pressure Transmitters can be used to measure liquid,Website:, gas or steam pressure. They output a 4 to 20 mA DC signal corresponding to the measured pressure.The models EJA438W and EJA438N feature remote setupand monitoring through communications with the modelBT200/100 BRAIN TERMINAL, CENTUM CS/XL systemetc. Specifications*1: Measurement range is within the flange rating.Output Signal “”:4 to 20 mA DC, 2-wire system with digital communicationFailure Alarm:Output status at CPU failure and hardware error;Up-scale: 110%, 21.6 mA DC or more(standard)Down-scale: -5%, 3.2 mA DC or less-2.5%, 3.6 mA DC or less (Optional code /F1)Note: Applicable for Output signal code D and ESupply Voltage “”:10.5 to 42 V DC for general use and flameproof type10.5 to 32 V DC for lightning protector (Optional code /A)10.5 to 30 V DC for intrinsically safe, Type n,nonincendive, or non-sparking type10.5 to 28 V DC for TIIS intrinsically safe typeConditions of Communication Line “”:Power supply voltage;16.4 to 42 V DCLoad resistance; See Figure 1.Note: In case of an intrinsically safe transmitter, externalload resistance includes safety barrier resistance.Communication distance;2 km, when CEV polyethylene-insulatedPVC-sheathed control cables are used.Note: Communication distance varies depends on kind ofcable.
