330101-00-16-10-02-05 | Bently Nevada | 3300 XL 8mm Proximity Probe

Product Overview

The 330101-00-16-10-02-05 represents a fundamental transducer component within the Bently Nevada 3300 XL Proximity Transducer System. This 100% Brand New original 8mm eddy-current probe provides non-contact 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 probe tip and the target shaft. It delivers high-accuracy data to 3300 XL Proximitor sensors, enabling predictive maintenance and emergency shutdown protection for turbines, compressors, and motors.

Engineering Advantages

• High-Resolution Vibration Tracking: The probe achieves a standard scale factor of 200 mV/mil. This sensitivity allows the monitoring system to capture minute shaft center-line displacements and orbital dynamics, which helps identify misalignment, rotor unbalance, or bearing wear before catastrophic failure occurs.

• Ruggedized Material Selection: The stainless steel case and polyphenylene sulfide (PPS) tip resist the chemical degradation caused by synthetic lubricants and high-pressure steam. This durability ensures the probe maintains its electrical gap settings during multi-year operation cycles in power plant and refinery applications.

• Precision Threaded Mounting: The 3/8-24 UNF threading provides fine adjustment control during the initial mechanical gap setting. This precise threading allows technicians to lock the probe into position with sub-mil accuracy, ensuring the sensor operates within the linear range of the 3300 XL Proximitor.

• Integrated Shielded Cable: The 1.0-meter integral cable utilizes high-performance shielding to reject electromagnetic interference (EMI) from nearby high-voltage motors or generators. This maintains a high signal-to-noise ratio, ensuring the vibration data remains clean and deterministic.

FAQs

• Is this 330101-00-16-10-02-05 probe a brand-new unit?

  Yes. We supply this probe as a 100% Brand New original Bently Nevada factory component. Each unit remains in its original protective packaging to guarantee factory-spec performance and calibration integrity.

• Do I need a specific extension cable for this 1.0m probe?

  Yes. For a standard 5-meter system, you must pair this 1.0-meter probe with a 4.0-meter 3300 XL extension cable. Always verify that the total system length (Probe + Extension Cable) matches the calibration of your 3300 XL Proximitor sensor.

• How should I handle the probe tip during installation?

  Never use a wrench on the probe tip or the plastic head. Apply torque only to the hexagonal flats on the stainless steel case. Avoid scratching the 8mm tip surface, as physical damage to the tip can alter the magnetic field distribution and invalidate the scale factor.

• Can this probe operate in high-temperature environments?

  The 3300 XL 8mm probe typically operates in temperatures ranging from -52 °C to +177 °C (-62 °F to +350 °F). This wide thermal envelope allows for direct installation within turbine bearing housings where high-temperature oil splash is common.
