1B. For a new spring-loaded installation, the overall sensor housing dimension “LL” is the sum of three numbers (See
Figure 2):
A. the connection length (N, NU, or NUN - from Part 1)
B. the thermowell bore length (“L” in Fig. 2) (sometimes referred to as the “A” dimension by well mfrs.)
C. the insertion into the head (1.5”). Add A, B and C.
2.
Measuring from the welded tip back, mark the stainless housing

Part 3:
Cut the sensor housing
Tools Needed:
tubing cutter, vise (or crimper)
Components Needed: housing
1. Place the housing stock into the tube cutter, aligning the cutting wheel with the mark for housing length.
2. Hold the end of the housing that is to be discarded in a vise. (If a vise is not available, you can use the crimp tool or vise
grips to hold the housing stock.)
3. Tighten the tube cutter blade onto the housing and with minimum pressure, rotate the tube cutter around the tube several
times, tightening the cutting wheel slightly after each turn. The housing should not turn with the tubing cutter. You want
to create a score through 50-75% of the wall thickness of the housing stock.
Avoid cutting completely through the housing wall. This can close the inner diameter of the tube and
prevent the pod from entering the housing.
4. Loosen the cutter and remove the housing from it.
5. Position your thumbs on either side of the groove and gently bend the housing back and forth until it breaks. If it does
not break easily do not use excessive force, but repeat the first part of the cutting procedure.
6. If a burr is created, remove it with the de-burring device on the tubing cutter.
