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.
