EJA438N Gauge Pressure Transmitters

                               EJA438N Gauge Pressure TransmittersFeatures :The main effect of the pressure transmitter pressure signals to the electronic device,Website:, and then the computer shows the pressure principle generally: the mechanical signal into a current pressure of this pressure (4-20mA) Such electronic signal pressure and voltage or the current size of a linear relationship is generally positive relationship. Therefore, the voltage or current output of the transmitter increases with pressure thereby obtain a two pressure measured media pressure and voltage or current relationship leads to high pressure transmitter, two low pressure chamber , low-pressure chamber pressure with atmospheric pressure or vacuum acting on the δ yuan (ie sensitive element) on both sides of diaphragm, is transferred to the measurement on both sides of the diaphragm and filling liquid through the spacer element within. Specifications : Accuracy:See Table 2.Ambient Temperature Limits:-40 to 60 ˚C (-40 to 140 ˚F) (general-use type)-30 to 60 ˚C (-22 to 140 ˚F) (with integral indicator)(Note: The ambient temperature limits must be within the fillfluid operating temperature range, see table 1.)(See ‘Optional Specifications’ for Explosion-protectedtypes)Ambient Temperature Effect:See Table 2.Process Temperature Limits:See Table 1.(See ‘Optional Specifications’ for Explosion-protectedtypes)Ambient Humidity Limits:5 to 100 % R.H.(at 40 ˚C)Working Pressure Limits:2.7 kPa abs{20 mmHg abs}to max. measurementrangevalue.(Note: The working pressure must be within flange ratingpressure.)For atmospheric pressure or below, see Figure 2.Power Supply Effect “”:0.005 %/V (21.6 to 32 V DC, 350 )Mounting:Transmitter; 2-inch pipe mountingDiaphragm seal; flange mounting Technical parameters :  Products show : Why chose us :
