Installation
If mounting the transmitter directly to the sensor assembly, use the process shown in
. If mounting the transmitter apart from the sensor assembly, use conduit between the sensor
and transmitter. The transmitter accepts male conduit fittings with

threads are provided
by an adapter). Make sure only qualified personnel perform the installation.
The transmitter may require supplementary support under high-vibration conditions, particularly if used
with extensive thermowell lagging or long extension fittings. Pipe-stand mounting, using one of the
optional mounting brackets, is recommended for use in high-vibration conditions.

Installation
2.5.1
Typical North American installation
1. Attach the thermowell to the pipe or process container wall. Install and tighten thermowells and
sensors, then apply process pressure to perform a leak test.
2. Attach necessary unions, couplings, and extension fittings. Seal the fitting threads with PTFE tape (if
required).
3. Turn the sensor into the thermowell or directly into the process (depending on installation
requirements).
4. Verify all sealing requirements for severe environments or to satisfy code requirements.
5. Attach the transmitter to the thermowell/sensor assembly. Seal all threads with PTFE tape (if
required).
6. Pull sensor leads through the extensions, unions, or couplings into the terminal side of the
transmitter housing.
7. Install field wiring conduit to the remaining transmitter conduit entry.
8. Pull the field wiring leads into the terminal side of the transmitter housing.
9. Attach the sensor leads to the transmitter sensor terminals. Attach the power leads to the
transmitter power terminals.
10. Attach and tighten both transmitter covers since both transmitter covers must be fully engaged to
meet explosion-proof requirements.
