Immersion Mounting
1. Reverse the compression fitting assembly on the sensor so that the longer
threaded section faces towards the sensor cable end (see Figure 2-4).
2. Position the compression fitting assembly at the far cable end of the sensor
body and tighten the compression nut onto the compression fitting. Use one
wrench to hold the fitting and another to turn the nut 1 to 1% turns to crimp
the ferrule. This provides a process seal.
- Installation
Installation Tip!
Re-using Compression Fitting, Nut, and Crimped Ferrule:
If the sensor is re-installed, the compression fitting and nut can be re-used. The
crimped ferrule, however, may need to be cut away from the sensor to remove it,
making it unusable. If you can remove the crimped ferrule without destroying it,
and if it can still provide an effective process seal, you can probably re-use it at
least the number of times listed below:
