330101-00-28-20-02-05 | Bently Nevada 8mm Proximity Probe | 3300 XL

Product Overview

The 330101-00-28-20-02-05 serves as a high-performance transducer for non-contacting vibration and position measurements. As a critical component of the Bently Nevada 3300 XL series, this 100% Brand New original 8mm probe monitors radial vibration and axial displacement on fluid-film bearing machines. It precisely converts the mechanical gap between the probe tip and the target shaft into a high-fidelity electrical signal. Designed for utility-scale turbines and industrial compressors, this configuration features a 2.8-inch threaded case and a 2.0-meter integral cable, providing the reach and hazardous area certifications required for demanding global energy projects.

Part Number Breakdown

Bently Nevada utilizes a specific alphanumeric coding system to define the mechanical profile and electrical certifications of the 3300 XL 8mm series.

• -28: Overall Case Length (2.8 inches / 71 mm)

• -20: Total Length (2.0 meters / 6.6 feet)

• -02: Connector Option (Miniature coaxial ClickLoc™ connector, standard cable)

• -05: Agency Approval (Multiple Approvals: CSA, ATEX, IECEx)

Technical Specifications

The 330101-00-28-20-02-05 maintains strict linearity and interchangeability across its entire operating range.

Engineering Advantages

• Extended Reach for Internal Installations: The 2.0-meter integral cable simplifies routing within large turbine bearing housings. This extra length allows technicians to position the ClickLoc™ connector outside of heavily contaminated oil splash zones, significantly reducing the risk of signal noise and connector degradation.

• Global Explosion-Proof Certification: The "-05" multi-approval option ensures compliance with ATEX and IECEx standards. This allows for seamless deployment in Zone 0, 1, or 2 hazardous environments, providing a single global part number for international refinery and offshore projects.

• Superior Signal Integrity: The ClickLoc™ connector system incorporates a positive mechanical lock. This design prevents unintentional disconnection caused by the extreme high-frequency vibrations typical of turbine decks, ensuring a continuous data stream for the monitoring system.

• Ruggedized Chemical Resistance: The PPS tip and stainless steel case withstand aggressive synthetic lubricants and high-pressure steam. This durability prevents "probe creep" or signal drift when exposed to the high-temperature chemical environments found in utility-scale power assets.

FAQs

• Is this 330101-00-28-20-02-05 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 the "Made in USA" designation to guarantee authenticity and performance.

• Which extension cable should I pair with this 2.0-meter probe?

  To achieve a standard 5.0-meter system length, you must use a 3.0-meter 3300 XL extension cable. For a 9.0-meter system, pair it with a 7.0-meter extension cable. Always ensure the total electrical length (Probe + Extension) matches the calibration of your Proximitor sensor.

• How does the ClickLoc™ connector improve reliability?

  The ClickLoc™ connector replaces standard friction-fit connectors with a threaded, locking mechanism. This prevents the cable from backing out due to machinery vibration, which is a common cause of "intermittent signal" alarms in older proximity systems.

• Can this probe handle high-temperature oil splash?

  The 3300 XL 8mm probe tip and case provide a pressure-tight seal and utilize materials rated for continuous operation up to +177°C. It functions reliably even when submerged or splashed by hot lubricating oils within the turbine pedestal.
