Expert FAQ & Selection Guide
What is “probe penetration” and why choose 5.0 inches?
It is how far the probe tip sticks out from the housing mount. Choose 5.0 inches (option 050) for standard applications where the shaft is not deeply recessed. It is a common, versatile length.
Can I adjust the probe position inside this housing?
Yes, the probe sleeve allows adjustment. The 5.0-inch specification is the maximum possible extension. You can set it to a shorter distance if needed.
What is the main difference between the -050 and -135 penetration models?
The -050 model has a 5.0″ maximum penetration. The -135 model has a longer 13.5″ penetration for reaching shafts that are set much deeper inside the machine casing.
Is the included 8mm probe interchangeable with an 11mm probe?
No. The housing sleeve is sized for the specified probe (8mm in this kit, option 16). To use an 11mm probe, you must order a different housing assembly model.
Do I need any other parts to complete the installation?
This kit includes the major components. You will need to supply the correct conduit, junction box, and possibly thread sealant for the NPT connections, following local electrical codes.
