Bently Nevada 330103-00-18-10-02-00 3300 XL 8mm Proximity Probe

Description

Engineered for continuous industrial vibration and shaft position monitoring, the Bently Nevada 330103-00-18-10-02-00 operates as a core transducer element within the 3300 XL 8mm Proximity Transducer System. This eddy current proximity probe delivers precise, non-contact measurements of static and dynamic shaft movement, making it indispensable for critical machinery protection systems. Its rugged mechanical design is optimized for high-pressure, fluid-film bearing environments typical of heavy rotating machinery.

Features

• Eddy Current Measurement: Highly accurate non-contact tracking of shaft displacement and vibration.
• ClickLoc Coaxial Connector: Features a robust, gold-plated miniature coaxial connection designed to resist vibration-induced loosening.
• Standard Cable Protection: Supplied with durable, high-performance coaxial cabling suitable for standard industrial environments.
• Thermal Stability: Retains high measurement linearity across broad operating temperature swings.
• Interchangeability: Fully compatible with standard 3300 XL Proximitor Sensors and extension cables.

Applications

• Steam and gas turbine shaft vibration and axial thrust position tracking.
• Centrifugal compressor radial dynamic motion monitoring.
• Heavy-duty gearbox and industrial pump bearing health assessment.
• Hydroelectric generator shaft runout and alignment verification.

Technical Specifications

Connections and Interfaces

This proximity probe terminates in a miniature gold-plated coaxial ClickLoc connector. It must be paired with a compatible 3300 XL extension cable to interface with the matching 3300 XL Proximitor Sensor.

Empirical Engineering Insights

Alternative Models & Compatibility

Because this probe is a 1.0-meter configuration, it is critical to pair it with a system engineered for the correct total electrical length (typically 5-meter or 9-meter systems). For a standard 5.0-meter calibration loop, this probe requires a 4.0-meter extension cable. Attempting to mix 1.0-meter probes with 9-meter extension cables without proper Proximitor recalibration will introduce severe non-linearity errors in the scale factor.

Application Pitfalls & Engineering Notes

Ensure adequate side clearance during installation. Standard 8mm probes require a minimum of 15.2 mm (0.6 inches) of clearance from adjacent metals. If the probe is mounted too close to a counterbore or bracket, the eddy current field will interact with the surrounding metal, causing false gap voltage readings and flattening the dynamic response curve.

Commissioning & Wiring Tips

Always use a connector protector or self-fusing silicone tape on the ClickLoc connection if the junction is exposed to oil mist or moisture inside the bearing housing. Before final tightening of the mounting nuts, verify the gap voltage using a digital multimeter at the Proximitor's "OUT" and "COM" terminals; a standard gap voltage of approximately -10 VDC corresponds to the midpoint of the linear range.
