Frequently Asked Questions

Why must the extension cable length exactly match the system calibration type?

Proximitor sensors rely on precise total electrical length to calculate eddy current displacement correctly. Mixing lengths changes loop capacitance, which introduces severe measurement errors into the final vibration reading.

What unique mechanical benefit does the patented ClickLoc connector interface provide?

The gold-plated brass ClickLoc mechanism physically locks the matching terminal ends together. This positive interlock prevents the cables from separating under continuous high-frequency machinery vibrations.

Can I apply standard silicone tape to this cable near turbine oil environments?

Do not use silicone tape if the connection point faces direct exposure to turbine lubrication oil. The oil can degrade the adhesive backing, so use the integrated connector protector instead.

How does the flexible AISI 302 SST armor layer enhance field reliability?

The stainless steel armor acts as a rugged shield against crushing forces and hot flying debris. It prevents physical punctures that could ground the internal triaxial shield layers.

What is the recommended method for verifying electrical continuity on this assembly?

Disconnect both ends and measure the DC resistance across the center core using a quality digital multimeter. A healthy 8-meter assembly must display a core resistance value within the strict 2.0 ± 0.5 Ohm range.
