IMPORTANT
• When welding piping during construction,
take care not to allow welding currents to
flow through the transmitter.
• Do not step on this instrument after
installation.
• For the EJX530B whose capsule code is A,
B or C, the pipe of the atmospheric opening
is located on the pressure detecting section.
The opening must not face upward. See
subsection 5.1.1.
• D capsule of EJX530B is of sealed gauge
reference and the change in atmospheric
pressure may affect the measurement.
4.2 Mounting
■ The impulse piping connection port of the
transmitter is covered with a plastic cap to
protect against dust. This cap must be removed
before connecting the piping. (Be careful not
to damage the threads when removing these
caps. Do not insert a screw driver or other
tool between the cap and the port threads to
remove the cap.)
■ The transmitter can be mounted on a nominal
50 mm (2-inch) pipe using the mounting bracket
supplied, as shown in Figure 4.1.
■ The user should prepare the mating gasket for
the transmitters with Process connection code
8 and 9. See Figure 4.2.
