Typical Universal Head Installation–head mount transmitter with
threaded sensor
1. Attach the thermowell to the pipe or process container wall. Install and tighten thermowells before
applying process pressure.
2. Attach necessary extension nipples and adapters to the thermowell. Seal the nipple and adapter
threads with silicone tape.
3. Screw the sensor into the thermowell. Install drain seals if required for severe environments or to
satisfy code requirements.
4. Verify the transmitter failure mode switch is in the desired position.
5. Pull the sensor wiring leads through the universal head and transmitter. Mount the transmitter in the
universal head by threading the transmitter mounting screws into the universal head mounting holes.
6. Seal adapter threads with thread sealant.
7. Pull the field wiring leads through the conduit into the universal head. Wire the sensor and power
leads to the transmitter (see
