Product details

1. General Introduction

EJA118E Diaphragm Sealed Differential Pressure Transmitters can be used to measure liquid, gas, or steam flow, as well as liquid level, density, and pressure. It's diaphragm seals are used to prevent process medium form entering directly into the pressure-sensing assembly, connected to the transmitter using capillaries filled with fill fluid, available for fluid with temperature -50 to 310°C.

5. Model and suffix codes

◆ Instruction

The model and suffix codes for EJA118E consist of two parts; a transmitter body section (I) and a diaphragm seal section (II). This specification sheet introduces these two parts separately. The transmitter body section is shown in one table, and the diaphragm seal section specifications are listed according to the process connection style. First select the model and suffix codes of transmitter body section and then continue on one of the diaphragm seal selection.

7. Ordering Information

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.

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) 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(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.

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.)
