Head Mount Transmitter with Threaded Sensor

The least complicated assembly uses:

a threaded sensor with flying leads

the universal connection head

a union and nipple extension assembly

a threaded thermowell

Refer to Volume 1 of the Rosemount Sensors Product Data Sheet (document number 00813-0100-2654) for complete sensor and mounting accessory information.

To complete the assembly, follow the steps as described below.

1. Attach the thermowell to the pipe or process container wall. Install and tighten thermowells before applying pressure.

2.Attach necessary extension nipples and adapters. 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.Set the transmitter failure mode switch (see Figure 2-13 on page 2-16).

5.Pull the sensor wiring leads through the extensions and adapters into the universal head. Mount the transmitter in the universal head by threading the transmitter mounting screws into the universal head mounting holes.

6.Mount the assembly into the thermowell. Seal adapter threads with silicone tape.

7.Install conduit for field wiring to the conduit entry of the universal head. Seal conduit threads with silicone tape.

8. Pull the field wiring leads through the conduit into the universal head. Attach the sensor and power leads to the transmitter. Avoid contact with leads and terminals.

9. Install and tighten the universal head cover. Enclosure covers must be fully engaged to meet explosion-proof requirements.
