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

The Bently Nevada 330101-00-28-05-02-00 is a precision-engineered component of the 3300 XL 8 mm Proximity Transducer System, one of the most widely adopted non-contact sensing solutions in the industrial world. Designed by GE’s Bently Nevada, this model offers a robust, accurate means of measuring shaft displacement and vibration for critical rotating machinery.

This proximity probe uses the eddy current principle to detect relative motion between the probe tip and the rotating shaft, delivering real-time feedback essential for condition monitoring and machinery protection systems. The 330101-00-28-05-02-00 features a 0.5 meter total length, and a 75-ohm connector, optimized for compatibility with a wide range of Proximitor sensors.

Technical Specifications

• Minimal Maintenance: Requires no recalibration and only basic periodic inspection.

• Extreme Environment Tolerance: Operates flawlessly under temperature extremes and in the presence of oil or moisture.

• Standardized Design: Simplifies inventory and replacement planning across facilities.

• API 670 Compliant: Suitable for use in API-compliant protection systems.

Frequently Asked Questions (FAQ)

1. What does the part number 330101-00-28-05-02-00 mean?

   It refers to a 3300 XL proximity probe with 0.5 meter total length and a 75-ohm connector.

2. What kind of sensor does this probe connect to?

   It connects to the Bently Nevada 3300 XL Proximitor Sensor.

3. What’s the benefit of a 28-inch probe length?

   It allows the probe to reach measurement points deep inside large equipment housings.

4. Can this model be used in hazardous environments?

   Yes, it’s built for harsh industrial settings and meets IP68 protection when properly assembled.

5. Is the probe field replaceable?

   Yes, but proper procedures and alignment checks must be followed during replacement.

6. What’s the difference between 50-ohm and 75-ohm connectors?

   The impedance must match the Proximitor Sensor; 75-ohm is often used for longer cable lengths or legacy systems.

7. Can it be used to measure both axial and radial motion?

   Yes, it supports both, depending on the installation orientation.

8. Does it need calibration?

   No user calibration is required. Factory calibration ensures long-term accuracy.

9. What maintenance does the probe require?

   Occasional visual inspection for damage or oil buildup is sufficient.

10. How long can this probe operate without failure?

    Many probes function reliably for 5–10 years, especially when installed correctly and in clean conditions.
