Bently Nevada 330101-00-30-10-02-00 3300 XL 8mm Proximity Probe

Product Overview

The 330101-00-30-10-02-00 functions as a high-precision eddy-current transducer within the Bently Nevada 3300 XL ecosystem. This 100% Brand New original 8mm probe provides non-contacting measurement of radial vibration and axial thrust position on fluid-film bearing machines. By generating a high-frequency magnetic field, the probe detects microscopic changes in the distance between the tip and the target shaft. This specific configuration features a 3.0-inch fully threaded case and a 1.0-meter integral cable, offering the necessary reach for deep bearing housing penetrations in utility-scale turbines and industrial compressors.

Technical Specifications

The 330101-00-30-10-02-00 utilizes high-grade materials to ensure signal linearity and mechanical resilience.

Engineering Advantages

• Extended Reach for Deep Access: The 3.0-inch threaded case enables the probe to reach internal shaft targets through thick bearing housings or machine casings. This long-reach design eliminates the need for custom spacers or complex mounting adapters, ensuring a direct and stable installation.

• High-Fidelity Linear Measurement: The 3300 XL system achieves superior linearity across its 80-mil range. This precision allows maintenance teams to track subtle shaft center-line changes and orbital dynamics, providing early warnings for misalignment or rotor unbalance.

• Vibration-Proof ClickLoc™ Connection: The ClickLoc™ miniature coaxial connector features a positive mechanical lock. This design prevents the cable from backing out due to high-frequency machinery vibrations, a common cause of "intermittent signal" or "Not OK" status in standard friction-fit proximity systems.

• Broad Thermal Envelope: The probe operates reliably from -34°C up to +177°C. This wide temperature range ensures stable performance within the high-heat zones of steam turbines and large induction motors without significant sensitivity drift.

FAQs

• Is this 330101-00-30-10-02-00 probe a brand-new unit?

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

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

  To achieve a standard 5.0-meter system length, you must pair this 1.0-meter probe with a 4.0-meter 3300 XL extension cable. For a 9.0-meter system, pair it with an 8.0-meter extension cable. Ensure the total electrical length matches the calibration of your Proximitor sensor.

• Can this probe operate in high-pressure oil environments?

  The 3300 XL 8mm probe features a pressure-tight seal between the probe tip and the connector. It effectively resists the ingress of lubricating oils and moisture typical of turbine pedestals. For extreme high-pressure applications, always verify the specific pressure ratings in the official system datasheet.

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

  Connect the probe to its Proximitor and monitor the DC output voltage. Adjust the 3/8-24 UNF threading until the voltage reads approximately -10.0 VDC, which corresponds to the center of the linear range for most 3300 XL applications.
