10.2 Model and Suffix Codes
 Instruction
The model and suffix codes for EJX118B and EJX438B 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 section.
