Professional FAQ

What is the difference between a 2.5-inch and 2.4-inch case?

The 2.5-inch case (option -25) is 0.1 inch longer than the standard 2.4-inch case (option -24). This may be required for specific mounting hole depths or OEM specifications.

Is the FluidLoc cable necessary for all 9-meter installations?

It is highly recommended for any damp environment to prevent signal issues. In consistently dry indoor settings, a standard cable may suffice.

Can this probe be used to measure axial thrust?

This is primarily a radial vibration probe. For axial thrust measurement, a different setup and potentially a different probe orientation are required. Consult your system manual.

How does the system compensate for the long cable's electrical characteristics?

The matching 9-meter Proximitor sensor is electronically calibrated for the specific resistance and capacitance of the 9-meter cable, ensuring accurate signal transmission.

What maintenance does the FluidLoc cable require?

Routine visual inspection for jacket damage. Ensure the ClickLoc connector and mating surface are clean and dry before connection to maintain the environmental seal.
