Bently Nevada 330103-05-15-10-02-00 3300 XL 8mm Proximity Probe

Product Overview

The 330103-05-15-10-02-00 represents the industrial standard for non-contacting vibration and displacement measurement. As part of the Bently Nevada 3300 XL 8mm series, this eddy current probe monitors critical machinery health by measuring the distance between the probe tip and the rotating shaft. It serves as a primary input for vibration monitoring systems in high-speed turbines, compressors, and pumps. We supply this unit as 100% Brand New original hardware, manufactured in the U.S.A., featuring global hazardous area approvals for mission-critical deployments.

Part Number Breakdown

The 3300 XL probe utilizes a specific nomenclature to define its mechanical and electrical configuration:

Technical Specifications

The 330103 series delivers high-resolution data for machinery protection systems:

• Sensor Type: Eddy Current Proximity Sensor

• Probe Tip Diameter: 8 mm

• Linear Range: 2.0 mm (80 mils) starting at approximately 0.25 mm (10 mils) gap

• Nominal Scale Factor: 7.87 V/mm (200 mV/mil)

• Operating Temperature: -51 °C to +177 °C (-60 °F to +351 °F)

• Connector: ClickLoc™ Gold-plated miniature coaxial connector

• Thread Type: 3/8-24 UNF-2A

Engineering Advantages

• ClickLoc™ Interconnect System: The proprietary ClickLoc™ connector prevents the cable from loosening during operation. This gold-plated connection resists corrosion and eliminates signal "spikes" caused by loose physical interfaces in high-vibration environments.

• Extreme Thermal Resilience: The probe handles extreme temperature fluctuations without significant drift in the scale factor. This ensures accurate vibration readings even during the startup and shutdown phases of thermal turbines.

• EMI/RFI Immunity: The 3300 XL system incorporates advanced shielding technology. This design allows for installation near high-voltage motors and variable frequency drives (VFDs) without electromagnetic interference corrupting the vibration signal.

• Oil-Impermeable Cable: The standard cable utilizes a material that resists degradation when exposed to common industrial lubricants and hydraulic fluids. This prevents internal short-circuits and maintains insulation integrity over the life of the machine.

• Global Compliance: The "-05" approval option provides peace of mind for international projects. It meets the safety requirements for North American (CSA), European (ATEX), and Global (IECEx) hazardous area classifications.

FAQs

Q: Does the 330103-05-15-10-02-00 require a specific Proximitor sensor?

A: Yes. You must pair this probe with a 3300 XL Proximitor Sensor (e.g., 330180 series). Using a non-XL proximitor will result in incorrect scale factors and inaccurate vibration data.

Q: What is the benefit of the 0mm unthreaded length option?

A: The "00" option means the probe body is fully threaded. This provides maximum flexibility during installation, allowing you to mount the probe into deep ports or through thin bracketry while maintaining full adjustability for gapping.

Q: Can I extend the 1.0m total length if the Proximitor is further away?

A: Yes, but you must use a matching 3300 XL Extension Cable. The total length of the probe plus the extension cable must match the calibrated length of the Proximitor sensor (typically 5.0 or 9.0 meters total).

Q: Is this probe compatible with older 3300 series (non-XL) systems?

A: While 3300 XL components are physically compatible with older 3300 hardware, we recommend replacing the probe, cable, and Proximitor together. Mixing XL and non-XL components may reduce the linear range and degrade the system's accuracy.
