Description

The Bently Nevada 330101-00-59-15-12-05 is a high-precision 8 mm proximity probe belonging to the industry-standard 3300 XL product family. This unique configuration features a fully threaded 5.9-inch stainless steel case (0.0 inches unthreaded length), a total probe length of 1.5 meters (4.9 feet), a specialized FluidLoc coaxial cable, a gold-plated miniature ClickLoc connector, and CSA, ATEX, and IECEx hazardous area approvals. Unlike configurations using standard cables, the FluidLoc option features a pressurized internal cable seal that blocks moisture, turbine oil, and other process gases from migrating along the inside of the coaxial core, providing an invaluable barrier in submerged or high-pressure installations. Because this model does not have protective armor, it provides a highly flexible cable profile for clean, tight routings within conduit and machine housings.

Operating as an eddy-current transducer, this probe performs non-contact vibration and static shaft position measurements. It interfaces directly with a 3300 XL extension cable and a 3300 XL Proximitor sensor (such as the 330180 series) to output a voltage signal directly proportional to the gap distance between the 8 mm PPS plastic probe tip and the observed target surface, typically an AISI 4140 steel shaft. The 3300 XL system delivers exceptional temperature stability and accuracy, meeting API 670 standards. This probe configuration is backward compatible with legacy, non-XL Bently Nevada 3300-series 5 mm and 8 mm components, enabling straightforward sensor replacement without requiring extensive modifications to existing monitoring chains.

Features

• Nominal 8 mm probe tip diameter with robust polyphenylene sulfide (PPS) encapsulation for maximum resistance to physical abuse and harsh oil-film environments.
• FluidLoc coaxial cable technology prevents oil, chemical, and moisture migration along the internal conductors of the cable.
• Gold-plated miniature coaxial ClickLoc connector enables a highly reliable connection without requiring specialized crimping or assembly tools.
• Fully threaded case (0.0 in unthreaded length) with standard 3/8-24 UNF threads and an overall case length of 5.9 inches for deep bearing housing insertions.
• 1.5-meter total probe length designed to integrate into standard 5-meter or 9-meter overall system configurations.
• Agency approval option 05 provides certified hazardous area compliance for ATEX, IECEx, and CSA installation zones.
• Rugged unarmored design offers greater cable flexibility and is optimized for installation in rigid external conduit systems.

Applications

This FluidLoc-equipped proximity probe configuration is ideal for high-vibration rotating machinery and applications where process fluids or lubricating oil migration is a concern. Common industrial applications include:

• Steam and gas turbine shaft vibration and axial displacement monitoring
• Compressor and high-pressure pump rotor position tracking
• Fluid-film bearing machines operating under high pressure or submerged conditions
• Keyphasor reference and speed measurements on high-speed rotating shafts
• Continuous industrial rotating machinery protection in oil and gas, petrochemical, and power generation plants

Ordering Information

The part number 330101-00-59-15-12-05 represents a highly specific orderable configuration of the 3300 XL 8 mm proximity probe. Each segment corresponds to a factory-defined physical specification detailed below:

Technical Specifications

Installation Guidelines

Adhering to these professional installation guidelines ensures reliable, long-term vibration measurements:

• Probe Gap Calibration: Mount the probe using a physical bracket or micrometer and verify the gap by monitoring the DC gap voltage at the Proximitor sensor. Set the voltage to the system's nominal calibration point (typically -10 Vdc for a mid-range gap).
• Thread Engagement Limits: Keep thread engagement within Bently Nevada limits. For 3/8-24 UNF threads, do not exceed a maximum engagement length of 0.563 inches to prevent thread binding or casing damage.
• Fluid Sealing Integrity: Ensure the Viton O-ring seal is clean and correctly positioned to maintain a robust pressure barrier. Avoid exposing the probe assembly to operating temperatures below -34 Celsius, which can lead to premature failure of the pressure seal.
• Routing and Shielding: Route the coaxial cable with proper shielding and grounding to mitigate electrical noise. Avoid routing cables over sharp metallic edges, and maintain the minimum allowable bend radius to preserve internal FluidLoc integrity.
