Installation
2.4.1
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.
