Description

330101-00-20-10-11-00 represents a Bently Nevada 3300 XL 8 mm proximity probe configuration featuring a fully threaded 3/8-24 UNF case with 0.0 in unthreaded length (Option 00) and a 2.0 in overall case length (Option 20). Built with a 1.0-meter total cable length (Option 10), this specific configuration incorporates a miniature coaxial ClickLoc connector with an integrated connector protector and FluidLoc cable (Option 11), requiring no agency approvals (Option 00) for general-purpose installations.

Compared to standard configurations using open connectors and standard cable designs, this variant includes the FluidLoc cable (Option 11) to block oil or other process fluids from migrating through the cable interior in pressurized applications. The fluorosilicone connector protector provides a robust seal over the ClickLoc coaxial connection, shielding it from moisture, contaminants, and mechanical friction. This unarmored probe operates on eddy-current principles to measure displacement, interfacing with a 3300 XL Proximitor sensor and extension cable in critical machinery protection loops.

Features

• FluidLoc Cable (Option 11): Seals the inner core of the coaxial cable to prevent lubricating oil or process gas migration along the cable path.
• Integrated Connector Protector: Pre-installed fluorosilicone sleeve shields the ClickLoc connection from environmental ingress and abrasion.
• Fully Threaded Body: 3/8-24 UNF threaded case with 0.0 in unthreaded length (Option 00) and 2.0 in total case length (Option 20) for versatile threading depth.
• 1.0-Meter Total Cable Length: Option 10 matches standard short-routing setups to reach nearby extension cables.
• Polyphenylene Sulfide (PPS) Tip: Durable probe tip material designed to withstand aggressive chemical exposures and extreme temperatures.
• Stainless Steel Case: AISI 303 or 304 stainless steel construction provides high mechanical strength and corrosion resistance.

Applications

• Turbine Vibration Monitoring: Shaft vibration and axial position monitoring on high-speed steam and gas turbines.
• Pressurized Bearings: Displacement measurements on centrifugal compressor or pump rotor shafts where oil seal containment is essential.
• General-Purpose Machine Protection: Continuous machinery condition monitoring in non-hazardous industrial areas where approvals are not required.

Installation Guidelines

• Probe Gap Setting: Install the probe with the appropriate physical gap relative to the target shaft (typically 1.27 mm or 50 mils) to achieve proper calibration within the linear range of the 3300 XL Proximitor sensor.
• Connector Handling: Hand-tighten the miniature coaxial ClickLoc connector prior to installing the protective fluorosilicone sleeve. Do not use excessive force or tools on the connector threads.
• Cable Routing: Observe the minimum cable bend radius of 25.4 mm (1.0 in) to prevent internal damage or changes in coaxial capacitance. Use proper conduit or mounting clamps to secure the cable and prevent whipping.
• Shielding and Grounding: Ensure the system shield is properly grounded at a single point, typically the monitor rack, and that the probe body is isolated from electrical noise source loops.
