    Yokogawa EJA118E Differential Pressure Transmitter With Remote Diaphragm Seals

    Yokogawa EJA118E Differential Pressure Transmitter with Remote Diaphragm Seals


    General Specifications

    Diaphragm seals are used to prevent process medium form entering directly into the pressure-sensing assembly

    of the differential pressure transmitter, they are connected to the transmitter using capillaries filled with fill fluid.

    EJA118E Diaphragm Sealed Differential Pressure Transmitters can be used to measure liquid, gas,or steam flow,

    as well as liquid level, density, and pressure. EJA118E outputs a 4 to 20 mA DC signal corresponding to the

    measured differential pressure.

    Its highly accurate and stable sensor can also measure the static pressure which can be shown on the integral

    indicator or remotely monitored via BRAIN or HART communications. Other key features include quick response,

    remote set-up using communications,and self-diagnostics.

    FOUNDATION Fieldbus, PROFIBUS PA and 1 to 5 VDC with HART (Low Power) protocol types are also available.

    EJA-E series models in their standard configuration, with the exception of the Fieldbus,PROFIBUS and Low Power

    types, are certified as complying with SIL 2 for safety requirement.

    Static Pressure Signal Range and Accuracy

    (For monitoring via communication or on indicator. Includes terminal-based linearity,hysteresis, and repeatability)

    Range

    Upper Range Value and Lower Range Value of the statice pressure can be set in the range between 0 and Maximum Working Pressure (MWP*). The upper range value must be greater than the lower range value. Minimum setting span is 0.5 MPa (73 psi).

    * : Maximum Working Pressure (MWP) is within flange rating pressure.
