Bently Nevada 330103-00-14-50-02-00 3300 XL 8 mm Proximity Probe

Description

Machinery protection and condition monitoring systems rely heavily on precise eddy current measurements, which the 330103-00-14-50-02-00 transducer sensor delivers as a core component of the Bently Nevada 3300 XL series. Designed for demanding industrial environments, this 8 mm proximity probe converts physical shaft vibration and position displacements into electrical signals for continuous asset monitoring and turbine supervisory instrumentation (TSI) systems.

Engineering features include a patented TipLoc molding method that forms an exceptionally durable bond between the probe tip and the probe body. The cable assembly is secured using a CableLoc design that provides a robust 330 N pull strength, minimizing the risk of detachment or signal loss caused by intense mechanical vibration or accidental routing strains. Equipped with a standard coaxial cable and a miniature ClickLoc connector, this probe simplifies integration with standard proximity sensor extension cables and driver modules.

This sensor is fully backward compatible, offering seamless electrical and mechanical interchangeability with legacy non-XL 8 mm proximity probes. This facilitates drop-in retrofits and system upgrades without requiring modifications to existing four-hole mounting patterns or extensive recalibration of legacy monitoring rack channels.

Features

• Patented TipLoc Molding: Establishes a chemical and physical bond between the probe tip and the case, preventing moisture ingress and mechanical separation.
• CableLoc Design: Offers 330 N (75 lbf) of pull-strength resistance at the cable-to-probe junction to withstand high-vibration applications.
• ClickLoc Coaxial Connector: Standard miniature coaxial connection provides a secure, low-loss link with positive click engagement.
• Legacy Compatibility: Fits standard 4-hole mounting patterns and maintains electrical calibration alignment with prior-generation 8 mm Bently Nevada systems.
• Corrosion Resistant Case: Constructed from high-grade stainless steel to resist corrosive environments commonly found in heavy process industries.

Applications

• Steam and gas turbine shaft vibration and axial position monitoring.
• Centrifugal and reciprocating compressor radial displacement sensing.
• High-speed industrial pump monitoring and predictive maintenance.
• Hydroelectric generator thrust bearing and thermal expansion measurements.
• General industrial rotating machinery diagnostics within TSI and Bently Nevada 3500 systems.

Technical Specifications

Installation Guidelines

• Mounting Torque: Do not exceed the maximum specified torque rating for 3/8-24 UNF threads when securing the probe case into the mounting bracket or machine housing.
• Bend Radius: Observe the minimum coaxial cable bend radius of 25.4 mm (1.0 inch) during routing to prevent core damage and signal degradation.
• Connector Protection: Ensure the ClickLoc connectors are completely dry and clean before mating. In high-moisture environments, use silicone connector protectors or sealing tape.
• Cable Routing: Route probe cables through dedicated, grounded metal conduits to isolate the sensor signals from high-voltage motor lines or electromagnetic interference (EMI).
