330101-00-55-05-02-05 | Bently Nevada | 3300 XL 8mm Proximity Probe

Product Overview

The 330101-00-55-05-02-05 represents a specialized, extra-long reach transducer designed for the most challenging industrial monitoring environments. As a core component of the Bently Nevada 3300 XL series, this 100% Brand New original 8mm probe provides non-contacting measurement of radial vibration and axial position. It precisely translates the mechanical gap between the probe tip and the shaft into a high-fidelity electrical signal for machinery protection. This specific configuration combines an extra-long 5.5-inch threaded case with a short 0.5-meter integral cable, making it the ideal solution for deep-access internal bearing housings where cable bulk must be minimized.

Technical Specifications

The 330101-00-55-05-02-05 maintains strict linearity and interchangeability across its entire 80-mil operating range.

Engineering Advantages

• Maximum Reach for Deep Pedestals: The 5.5-inch fully 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.

• Streamlined Internal Routing: The 0.5-meter (1.6 feet) integral cable provides a compact connection point within the machine casing. This short length eliminates excess wire bulk, reducing the risk of cable snagging or vibration-induced wear within the oil-rich environment of the bearing housing.

• 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™ Connection: The ClickLoc™ miniature coaxial 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.

FAQs

• Is this 330101-00-55-05-02-05 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 0.5-meter probe?

  To achieve a standard 5.0-meter system length, you must pair this 0.5-meter probe with a 4.5-meter 3300 XL extension cable. For a 9.0-meter system, pair it with an 8.5-meter extension cable. Always verify that the total electrical length 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.
