Bently Nevada 330104-00-11-10-02-05 3300 XL 8 mm Proximity Probes

The Bently Nevada 330104-00-11-10-02-05 is a premium proximity probe from the 3300 XL 8 mm series, engineered for accurate, non-contact measurement of shaft position and vibration in rotating machinery. As part of GE’s Bently Nevada machinery protection portfolio, this model delivers precise displacement readings for real-time monitoring of critical equipment like turbines, compressors, motors, and pumps.

With an 8 mm sensing tip, M10 x 1 threaded body, and an integral 1.1-meter cable, this model provides high reliability and ease of installation in both OEM and retrofit environments. The “3300 XL” system—consisting of the probe, extension cable, and Proximitor® sensor—is factory-matched for exceptional accuracy and long-term signal integrity.

Designed to perform in high-temperature, high-vibration, and electrically noisy environments, this probe helps prevent costly failures by enabling predictive and preventive maintenance strategies.

Frequently Asked Questions (FAQ)

1. What is the main function of this probe?

   It measures the distance between the probe tip and a metal surface (typically a rotating shaft) without physical contact.

2. Is this model part of a complete monitoring system?

   Yes. It is used with a matching extension cable and Proximitor® sensor as part of the 3300 XL system.

3. Can it be used in high-temperature areas?

   Yes, it supports operating temperatures up to 177°C (350°F).

4. What’s the difference between this and a 5 mm probe?

   The 8 mm probe offers a longer linear range and is suited for standard installations with more space.

5. How is this probe installed?

   It’s mounted using its threaded body and secured with a lock nut; alignment and gap spacing are critical.

6. Is the cable replaceable?

   No, the integral cable is permanently attached. Any damage requires replacing the entire probe.

7. Can it be used in hazardous areas?

   The probe itself is not intrinsically safe, but the system can be made compliant with proper certified components.

8. What target materials are supported?

   Factory calibration is based on 4140 steel. Other materials may affect sensitivity unless recalibrated.

9. Is the connector shielded?

   Yes, the coaxial connector is shielded against electrical noise and must be properly sealed.

10. How does it interact with the Proximitor® sensor?

    It transmits the signal from the sensing tip through the extension cable to the Proximitor® module for signal processing.
