Installation & Handling Notes
Install using the 1/2-20 UNF thread. Engage up to 0.75 inches of thread. Tighten to 15.2 N•m. Connect the FluidLoc cable with the ClickLoc connector—hand-tight is enough. Route the armored cable to avoid extreme bends (stay above 1-inch radius). The FluidLoc feature is active once connected; ensure connectors are clean and dry before assembly.

Frequently Asked Questions
How does the FluidLoc cable actually work?
It uses a special sealing design within the cable and connector. This creates a barrier that blocks fluids from traveling through the cable’s interior, preventing them from reaching the machine casing or sensor.
Can I use this 5-meter probe with a 9-meter Proximitor system?
No. The product note states it is for use with the 5-meter Proximitor only. Using mismatched lengths will cause calibration and performance errors.
What is the main advantage of the armor?
The stainless steel braided armor protects the inner cable from being cut, crushed, or worn through by abrasion. This is critical in areas with moving parts or rough surfaces.
Is the Viton O-ring chemical resistant?
Viton has good resistance to many oils, fuels, and chemicals. However, for specific aggressive chemicals, you should verify compatibility or contact Bently Nevada for custom options.
The specs warn about cold temperatures. Why?
The elastomer in the pressure seal can become brittle and crack if frozen below -34°C. If your machine operates in very cold conditions, consider warm tracing or insulation for the probe body.
Expert Selection Tips
Choose this 330707-00-20-50-12-00 model when you need both cable armor and fluid sealing. First, confirm your system uses a 5-meter Proximitor. Second, verify your mounting hole is 1/2-20 UNF. This is the premium choice for harsh, wet, or high-abuse environments.
