330101-00-28-10-02-00 | Bently Nevada 3300 XL 8mm Proximity Probe

Product Overview

The 330101-00-28-10-02-00 functions as a cornerstone transducer within the Bently Nevada 3300 XL Proximity Transducer System. This 100% Brand New original 8mm eddy-current probe provides non-contact measurement of radial vibration, axial thrust, and shaft position for critical rotating machinery. Manufactured in the U.S.A., it delivers the industry-standard scale factor and interchangeability required for fluid-film bearing machines. By capturing microscopic shaft movements, the probe enables the Proximitor sensor to provide high-fidelity data for early fault detection in steam turbines, centrifugal compressors, and large industrial motors.

Technical Specifications

The 330101-00-28-10-02-00 utilizes high-grade materials to maintain structural integrity and signal accuracy in aggressive industrial environments.

Engineering Advantages

• Enhanced Thermal Stability: The polyphenylene sulfide (PPS) tip resists the chemical degradation and thermal expansion caused by hot lubricating oils. This stability ensures the probe maintains a consistent electrical gap setting even during prolonged operation at peak turbine temperatures.

• Vibration-Proof ClickLoc™ Connection: The ClickLoc™ miniature coaxial connector features a positive-lock mechanism. This design prevents the cable from loosening under the high-frequency vibrations typical of turbine decks, maintaining a continuous, noise-free signal path.

• Precision Extended Case Length: The 2.8-inch fully threaded case accommodates deep bearing housing penetrations. This allows technicians to reach the shaft center-line in complex machinery configurations while retaining sub-mil adjustment precision for gap setting.

• Mechanical Resilience: AISI 303 stainless steel construction protects the internal sensor coils from high-pressure steam and corrosive atmospheres. This ensures the probe survives multi-year maintenance cycles without signal drift or structural failure.

FAQs

• Is this 330101-00-28-10-02-00 probe a brand-new original unit?

  Yes. We supply this probe as 100% Brand New original factory stock. Each unit arrives in its original Bently Nevada protective packaging with the "Made in U.S.A." designation to guarantee authenticity and performance.

• Which extension cable should I pair with this 1.0-meter probe?

  For a standard 5.0-meter system, you must use a 4.0-meter 3300 XL extension cable. For a 9.0-meter system, use an 8.0-meter extension cable. Ensure the total electrical length (Probe + Extension) matches the calibration requirements of your 3300 XL Proximitor sensor.

• Can I replace an existing probe without recalibrating the Proximitor?

  Bently Nevada manufactures the 3300 XL series to strict tolerances that allow for the replacement of probes without the need for manual system re-calibration. This "plug-and-play" capability reduces maintenance downtime during outages.

• How do I set the correct mechanical gap during installation?

  Utilize the 3/8-24 UNF threading to adjust the probe position while monitoring the DC Gap voltage at the Proximitor. For a standard system, adjust the probe until the voltage reads approximately -10.0 VDC, indicating the center of the linear range.
