• Attach thermowell (1) to pipe or process container wall. Install and tighten the thermowell before
applying process pressure.
• Attach necessary extension nipples and adapters (3) to the thermowell (1). Seal the nipple and
adapter threads with silicone tape.
• Screw the sensor (2) into the thermowell (1). Install drain seals if required for harsh environments
or to satisfy code requirements.
• Screw the connection head (4) to the sensor assembly.
• Attach the sensor lead wires to the connection head terminals.
• Connect sensor wires from the terminals inside the head to the TMT 122 transmitter (5).
• Install and tighten the connection head cover. Enclosure covers must be completely engaged to
meet explosion-proof area requirements.
