CDE681 Part 2 - 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:

2.2Immersion 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.
