Customer-supplied pipe nipple sensor mounting
If you can’t mount the sensor flush with the process as described in the
previous section (for example, the process wall is curved sharply, covered
with insulation, or obstructed with reinforcing members) you can instead:
1. Weld a short 3 1/2” diameter pipe nipple to the process wall and make
sure to extend the nipple through the skin of the process (see Figure
3-8).

2. Weld the 7” x 7 5/8” (17.78 cm x 19.37 cm) supplied plate to the end of
the nipple, taking care to center it over the hole
3. Wrap the nipple with at least 1” (2.54 cm) weatherproof insulation and
heat trace it.
4. Bolt the sensor to the plate.
If mounting the sensor using this method, you can also install the probe
heater to minimize the possibility of the sample gas cooling below its dew-
point.
