Bently Nevada 330101-00-79-15-02-05 3300 XL 8mm Proximity Probe

Product Overview

The 330101-00-79-15-02-05 represents the extreme-reach transducer solution within the Bently Nevada 3300 XL ecosystem. This 100% Brand New original 8mm probe provides non-contacting measurement of radial vibration, axial thrust, and shaft position for fluid-film bearing machines. It precisely detects the distance between the probe tip and the target shaft surface, converting mechanical displacement into a high-fidelity electrical signal. This specific configuration features a specialized 7.9-inch fully threaded case and a 1.5-meter integral cable, providing the physical reach and global hazardous area certifications required for the deepest bearing housing penetrations in utility-scale turbines.

Technical Specifications

The 330101-00-79-15-02-05 maintains strict linearity and interchangeability across its entire 80-mil operating range.

Engineering Advantages

• Extreme Reach for Deep Pedestals: The 7.9-inch threaded case facilitates installation through exceptionally thick machine casings or deep internal bearing pedestals. This length allows engineers to reach internal shaft targets while retaining sub-mil adjustment precision for final mechanical gap settings.

• Global Explosion-Proof Compliance: The "-05" multi-approval option ensures compliance with CSA, ATEX, and IECEx standards. This allows for immediate deployment in Zone 0, 1, or 2 hazardous locations, simplifying international procurement and ensuring adherence to global safety mandates.

• Vibration-Proof ClickLoc™ Technology: The miniature coaxial ClickLoc™ connector incorporates a positive-locking mechanism. This prevents unintentional cable disconnection or signal attenuation caused by high-frequency machinery vibrations, a common failure point in standard friction-fit proximity systems.

• Superior Signal Integrity: The 3300 XL series rejects electromagnetic interference (EMI) through high-performance cable shielding. This ensures that the vibration waveforms remain deterministic and clean, even when the probe operates near high-voltage generators or large induction motors.

FAQs

• Is this 330101-00-79-15-02-05 probe a brand-new unit?

  Yes. We supply this probe exclusively as 100% Brand New original factory stock. Each unit arrives in Bently Nevada’s original protective packaging with all factory inspection markings to guarantee authenticity and field reliability.

• Which extension cable should I pair with this 1.5-meter probe?

  To achieve a standard 5.0-meter system length, you must use a 3.5-meter 3300 XL extension cable. For a 9.0-meter system, pair it with a 7.5-meter extension cable. Always ensure the total electrical length (Probe + Extension) matches the calibration of your Proximitor sensor.

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

  Adjust the 3/8-24 UNF threading while monitoring the DC Gap voltage at the Proximitor output. For most 3300 XL applications, a voltage reading of approximately -10.0 VDC indicates the center of the linear range.

• Can this probe handle high-temperature oil splash?

  The 3300 XL 8mm probe utilizes high-grade stainless steel and PPS tip materials. It functions reliably even when submerged or splashed by hot lubricating oils within turbine bearing pedestals up to its rated operating temperature of +177°C.
