Bently Nevada 330101-00-75-15-02-05 3300 XL 8mm Proximity Probe

Product Overview

The 330101-00-75-15-02-05 represents the extreme-reach variant of the Bently Nevada 3300 XL transducer system. This 100% Brand New original 8mm probe provides non-contacting measurement of radial vibration, axial thrust, and shaft position for large-scale fluid-film bearing machines. Manufactured in the U.S.A., it translates mechanical displacement into a high-precision electrical signal for critical machinery protection. This specific configuration features an exceptional 7.5-inch fully threaded case and a 1.5-meter integral cable, providing the maximum physical reach and global hazardous area certifications required for the deepest bearing housing penetrations in utility-scale turbines.

Technical Specifications

The 330101-00-75-15-02-05 maintains strict linearity and interchangeability across its entire 80-mil operating range.

Engineering Advantages

• Extreme Reach for Large Machine Pedestals: The 7.5-inch threaded case enables the probe to reach internal shaft targets through exceptionally thick machine casings or deep internal bearing pedestals. This length allows engineers to reach recessed targets without custom mounting sleeves, retaining sub-mil adjustment precision.

• 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, providing a single global part number for international refinery and offshore projects.

• 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 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 330101-00-75-15-02-05 probe a brand-new original 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.
