Overview Manuals Specifications Application Diagnostics & System Installation & Upgrade

Features:

  • Meets mechanical and temperature stability standards; works with non-XL 3300 series components.
  • Patented TipLoc and CableLoc provide 330 N pull strength; gold-plated ClickLoc connectors resist loosening.
  • Includes CSA, ATEX, IECEx approvals (option 05); high RFI immunity eliminates shielded conduit.
The 330101-01-50-10-02-05 is fully certified to API 670 standards for linear range, accuracy, and temperature stability. This ensures reliable performance in critical turbomachinery monitoring. Additionally, it is electrically and physically interchangeable with non-XL 3300 series 5 mm and 8 mm components, allowing seamless upgrades or replacements without bench calibration. This flexibility reduces downtime and simplifies spare parts management, as the probe can be mixed with existing legacy systems while maintaining backward compatibility.

Built with patented TipLoc molding, the 330101-01-50-10-02-05 ensures a robust bond between the probe tip and body. The CableLoc design provides 330 N pull strength, preventing cable detachment under stress. Gold-plated ClickLoc connectors require only finger tightening and resist corrosion and loosening due to vibration. The included connector protector adds environmental sealing, making this probe ideal for industrial settings exposed to oil, moisture, or physical abuse. Its 177°C temperature rating further supports demanding applications.

With agency approval option 05, the 330101-01-50-10-02-05 is certified for use in CSA, ATEX, and IECEx hazardous locations. The Proximitor sensor offers enhanced RFI/EMI immunity, complying with CE mark requirements without special shielded conduit or metallic housings. This lowers installation costs and complexity, especially in generator or motor bearing monitoring. The probe’s standard 5.0-meter length and 3/8-24 UNF thread fit most mounting brackets, including phenolic types for additional electrical isolation.

The 330101-01-50-10-02-05 Bently Nevada Proximity Probe may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL)by the manufacturer (OEM).

  • Radial Vibration Monitoring: Installed in pairs at 90 XY orientations on bearing housings to track dynamic shaft centerlines and orbits.
  • Axial / Thrust Position Tracking: Measures micro-inch axial movements of a turbine or compressor rotor to prevent rotor-to-stator mechanical friction.
  • Keyphasor® & Phase References: Captures once-per-turn reference events on shafts to facilitate vibration analysis, component balancing, and precise RPM speed metering.
  • "NOT OK" Circuit Diagnostics: If the 1-meter coaxial cable becomes pinched, shorted, or disconnected from the extension cable, the host monitoring system (e.g., Bently Nevada 3500) registers a "NOT OK" hardware state.
  • False Trip Prevention: When a "NOT OK" diagnostic flag drops, the 3500 rack automatically bypasses the channel's machine-trip relays. This prevents physical sensor breaks from inducing catastrophic accidental plant shutdowns.
  • Advanced Tip & Cable Integrity: Built via patented TipLoc™ molding and CableLoc™ anchoring methods, the assembly yields a 330 N (75 lbf) maximum pull strength. This keeps the physical probe tip from pulling loose when subjected to extreme high-velocity process fluids.
  • Mechanical Clearance & Side-Wall Interference: Because the probe generates an unshielded radio-frequency (RF) field, it requires a minimum diameter of clear space around the tip. Keep a clearance of at least three probe tip diameters away from any surrounding metal structure to prevent false scaling offsets.
  • Precise DC Gap Calibration: Thread the probe into its mounting bracket while monitoring the Proximitor's output using a digital multimeter. For standard radial vibration on AISI 4140 steel, set the probe gap to a physical distance where the output reads -9.0 Vdc (the nominal midpoint of its 2.0 mm / 80 mil linear range).
  • Cable Splice Protection: Snap the miniature ClickLoc™ coaxial connector firmly into the matching extension cable. Slide a silicone connector protector sleeve over the physical connection to insulate the outer triaxial shield from making contact with the machine chassis.
Description
The 3300 XL 8 mm Proximity Transducer System provides an output voltage proportional to the distance between the probe tip and a conductive surface. A key example is 330101-01-50-10-02-05, which includes a 3/8-24 UNF threaded probe without armor, designed for high-density installations. 

The system supports both standard and FluidLoc cable options, with gold-plated ClickLoc connectors that require only finger tightening. For instance, 330101-01-50-10-02-05 uses connector protector option "10" and standard cable, ensuring environmental protection and robust field wiring. 

All components, including 330101-01-50-10-02-05, are fully interchangeable with non-XL 3300 series 5 mm and 8 mm parts. The probe features patented TipLoc and CableLoc molding, providing 330 N (75 lbf) pull strength. 

For extended temperature needs, ETR probes are available, but standard versions like 330101-01-50-10-02-05 support up to 177°C (350°F). The system meets API 670 standards for linear range and accuracy.
