330103-00-22-50-12-RU is a Bently Nevada eddy current proximity probe featuring an M10x1 metric thread and a continuous 5.0-meter FluidLoc cable. Fully compatible with deep-bore machinery housings, this unit works seamlessly with 3300 XL Proximitor sensors to deliver high-pressure fluid containment and stable industrial network communication.
Specifications
Unthreaded Length Option：0.0 in
Overall Case Length Option：160 mm
Total Length Option：5.0 meters (16.4 feet)
Connector and Cable-Type Option：Miniature coaxial ClickLoc connector, FluidLoc cable
Dimensions：116x1.8x1.8cm

Specific Application
- Continuous shaft displacement and radial vibration tracking inside deep-hole fluid-film bearing housings on heavy-duty machinery.
- Proximity measurement loops where the leading cable must pass through internal machine environments subject to constant oil mist or splashing.
- Machinery safety configurations inside specialized regional processing facilities requiring localized industrial regulatory approvals.
Competitive Advantage
- Advanced Fluid Containment: Incorporates a patented FluidLoc cable internal structural design that seals the core wire path, completely stopping oil or pressurized process liquids from escaping the machine housing through the cable's interior.
- Direct Hardware Integration: Features a continuous 5.0-meter electrical cable length that links straight to the core processing unit without relying on middle extension lines, removing insertion path contact resistance and lowering structural assembly cost.
- Optimized Case Length: Tailored with a deep 220mm fully threaded metric shank body that allows field maintenance teams to deploy baseline gapping parameters through thick mechanical isolation shells without needing customized extension sleeves.

Installation & Troubleshooting FAQ
Q1: What are the tightening torques and thread limits for mounting this 220mm long metric probe barrel?
A: Secure the probe case using an 8mm wrench flat profile and torque the casing to a recommended nominal field installation value of 11.2 N•m (100 in•lbf). Do not exceed the maximum rated hardware limit of 33.9 N•m (300 in•lbf). To prevent thread binding or mechanical sticking during installation through thick bearing frames, ensure the maximum length of active thread engagement inside the tapped hole does not exceed the metric engineering standard limit of 15 mm.
Q2: What unique benefit does the FluidLoc option code '12' bring to the physical cable configuration?
A: The '12' option code designates a miniature coaxial ClickLoc connector paired with a specialized FluidLoc cable. This design features a proprietary internal sealing matrix that plugs the raw wire spaces, completely preventing turbine oil or pressurized lubricants from leaking out of the machine housing through the cable's interior. Note that FluidLoc cables have a slightly larger outside diameter of 3.94 mm (0.155 in) compared to the 3.68 mm (0.145 in) specification of standard unsealed lines.
Q3: Why is it critical that this 5.0-meter probe connects directly to a 5-meter Proximitor sensor?
A: Proximity transducer systems function as resonant RF circuits that require their combined electrical length (integral probe cable plus any extension cable) to match the total calibrated length of the Proximitor sensor. Because this specific probe configuration has a 5.0-meter integral trailing line, it contains the entire electrical length required by a 5-meter Proximitor sensor and must bypass external extension cables completely to avoid loop tuning errors and scale factor distortion.
Q4: My system reports an unstable voltage output when tracing a small shaft target area. What is the cause?
A: For optimal tracking performance with an 8mm probe tip, the minimum recommended shaft diameter target is 76.2 mm (3.0 in), with an absolute lower operating limit of 50.8 mm (2.0 in). Running the sensor over target profiles narrower than these thresholds introduces edge effect interference and shifts the system scale factor away from its standard 7.87 V/mm (200 mV/mil) parameter rating.
