      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 V DC with HART (Low Power) protocol types are also available. All 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.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.EJA110E differential pressure transmitter can be used to measure the flow, level, density and pressure of liquid, gas or steam. The EJA110E high performance differential pressure transmitter is suitable for measuring the flow, level, density and pressure of liquid, gas or steam and converting it into the current signal output of 4~20mA DC. It has the functions of fast response, remote setting and self-diagnosis. The EJA-E series supports BRAIN, HART/HART (1-5V) low power consumption and FOUNDATION? Fieldbus or PROFIBUS PA communication protocol. 

      Specify the following when ordering
      1. Model, suffix codes, and option codes.
      2. Calibration range and units:
      1) Calibration range can be specified with range value specifications up to 5 digits (excluding any decimal point) for low or high range limits within the range of -32000 to 32000. When reverse range is designated, specify LRV as greater than URV. When square root output mode is specified, LRV must be “0(zero)”.
      2) Specify only one unit from the table, ‘Factory setting.’
      3. Select linear or square root for output mode and display mode.
      Note: If not specified, the instrument is shipped set for linear mode.
      4. Display scale and units (for transmitters equipped with the integral indicator only) Specify either 0 to 100 % or ‘Range and Unit’ for
      engineering units scale:
      Scale range can be specified with range limit specifications up to 5 digits (excluding any decimal point) for low or high range limits within the range of -32000 to 32000. Unit display consists of 6-digit, therefore, if the specified scaling unit excluding ‘/’ is longer than 6-characters , the first 6 characters will
      be displayed on the unit display.
      5. HART PROTOCOL
      When output signal code is “J”, specify the HART protocol revision “5” or “7”.
      6. TAG NO (if required)
      Specified characters (up to 16 characters for BRAIN, 22 characters for HART, or 16 characters for /N4 tag) are engraved on the stainless steel tag plate fixed on the housing.

      7. SOFTWARE TAG (for HART only. if required) Specified characters (up to 32 characters) are set as “Tag” (the first 8 characters) and “Long tag”*1 (32 characters) in the amplifier memory. Use alphanumeric capital letters. When the “SOFTWARE TAG” is not specified, specified “TAG NO” is set as “Tag” (the first 8 characters) and “Long tag”*1 (22 characters) in the amplifier memory.
      *1: applicable only when HART 7 is selected.
      8. Other factory configurations (if required) Specifying option code CA or CB will allow further configuration at factory. Following are configurable items and setting range. 
      [/CA : For HART communication type]
      1) Descriptor (up to 16 characters).
      2) Message (up to 30 characters).
      3) Software damping (0.00 to 100.00 s).
      [/CB : For BRAIN communication type]
      1) Software damping (0.00 to 100.00 s).
      9. Process fluid temperature for zero compensation (When /R is specified.)
