    Yokogawa EJA110A Differential Pressure Transmitter Functional Specifications

    Date:2017-12-12 

    Model EJA110A must be the master to measure liquid, gas,or steam flow as well as liquid level, density and pressure. How does it work? let's see its funtional spections.


    Zero Adjustment Limits


    Zero can be fully elevated or suppressed, within theLower and Upper Range Limits of the capsule.


    External Zero Adjustment


    External zero is continuously adjustable with 0.01 %incremental resolution of span. Span may beadjusted locally using the digital indicator with rangeswitch.


    Mounting Position Effect


    Rotation in diaphragm plane has no effect. Tilting up to90 ? will cause zero shift up to 0.4 kPa {1.6 inH2
    O}which can be corrected by the zero adjustment.

    Output

    Two wire 4 to 20 mA DC output with digital communications,linear or square root programmable. BRAINor HART FSK protocol are superimposed on the 4 to20 mA signal.

    Failure 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 (Optionalcode /F1)

    Note: Applicable for Output signal code D and E

    Damping Time Constant (1st order)

    The sum of the amplifier and capsule damping timeconstant must be used for the overall time constant.Amp damping time constant is adjustable from 0.2 to64 seconds.
