330101-00-08-10-11-CN FluidLoc Coaxial Cable Bently Nevada

Product Overview

The 330101-00-08-10-11-CN is an industrial-grade 3300 XL series 8 mm eddy current proximity probe manufactured by Bently Nevada for heavy-duty machinery diagnostics. Weighing 246 g (8.67 oz), this high-precision transducer features a compact 0.8-inch threaded case length with a 1.0-meter (3.3 feet) integrated FluidLoc coaxial cable. 

Core Technical Advantages

• Detailed Suffix Logic Breakdown:
  • 330101: Identifies the standard 3300 XL 8 mm proximity probe configuration with standard 3/8-24 UNF threads.
  • -00-: Selects 0 inches of unthreaded main body length, making the entire barrel surface threaded.
  • -08-: Specifies a compact 0.8-inch overall case length optimized for low-clearance or tight-access machine ports.
  • -10-: Configures a total physical and electrical probe cable length of 1.0 meter (3.3 feet).
  • -11-: Combines a miniature coaxial ClickLoc connector with an integrated protector sleeve on a FluidLoc oil-sealed cable.
  • -CN-: Establishes region-specific hazardous area and safety agency product certifications.
• FluidLoc Media Protection: The internal coaxial cable layers are manufactured with patented FluidLoc blocking technology, preventing liquid process contaminants, lubricating oils, and moisture from wicking through the line into dry terminal enclosures.
• Mechanical G-Force Resilience: Internally fortified to sustain continuous, multi-axis shock and mechanical vibrations up to a maximum rating of 20 g without experiencing signal clipping or structural casing fatigue.
• Integrated ClickLoc Guard: Shipped with a factory-installed connector protector over the miniature coaxial ClickLoc tip, neutralizing friction damage and stopping moisture ingress at critical cable joins.

Installation & Maintenance Guide

Case Mounting and Safe Torque Boundaries

Isolate the machine before installation. Thread the 0.8-inch case into the mounting sleeve or machine port manually to prevent cross-threading. When setting the final mechanical gap, do not exceed the maximum allowable installation torque limit of 11.3 N·m (100 in·lb) for the 3/8-24 UNF threads. Tightening beyond this can warp the internal coils and throw off calibration.

Coaxial Cable Routing and Bend Limits

Route the FluidLoc cable carefully away from high-voltage conduit lines. Maintain a strict minimum bend radius of 25 mm (1 inch) at all structural corners and junction box entry feeds. Kinking or pulling the cable tight risks separating the internal foil shields, leading to data errors and signal drift.

ClickLoc Link Interfacing and Protectors

The miniature ClickLoc coaxial connector joins to extension leads with a secure, tactile push-click action. Connectors should be locked clean and dry, finger-tight only. Ensure the integrated connector protector is pushed into place over the joint to seal out oil mist and moisture in harsh open-chassis environments.

Engineering Advantages

• High Temperature Survival: Built with robust polymers that handle continuous ambient temperatures up to 125°C (257°F), preventing sensor degradation in hot bearing casings.
• Low-Clearance Compatibility: The short 0.8-inch case format provides a reliable solution for tight internal clearances, where longer probe bodies would hit machine components.
• Stable Calibration Field: Delivers a clean linear output when calibrated against standard AISI 4140 steel targets, maintaining a consistent scale factor across its full measuring range.
• Regional Compliance Security: The specialized -CN extension ensures full country-specific compliance and safety approvals for hazardous industrial environments.

Technical FAQs

Q1: Can I connect this 1.0-meter probe directly into a 3300 XL Proximitor sensor loop?
A1: Yes, but the system requires a total electrical length of either 5.0 meters or 9.0 meters. This 1.0-meter probe must be matched with a corresponding 4.0-meter or 8.0-meter 3300 XL extension cable to ensure correct output calibration.

Q2: What is the main benefit of the FluidLoc cable option (-11-)?
A2: FluidLoc cable stops oil, water, or process fluids from leaking through the inside of the cable jacket if the outer sheath gets cut. This protects your external junction boxes from fluid contamination.

Q3: How do I know if the probe has been damaged by high vibration levels?
A3: If vibrations exceed the 20 g limit, check the DC resistance of the probe. Use a digital multimeter to measure between the center conductor and outer shield; standard resistance should match the values outlined in your main system reference manual.
