Bently Nevada 330709-000-130-10-02-00 3300 XL 11 mm Proximity Probe

The Bently Nevada 330709-000-130-10-02-00 is part of the 3300 XL series of proximity transducer systems, specifically engineered to provide highly accurate, non-contact displacement measurements for rotating machinery. This particular model is an 11 mm proximity probe, designed to measure shaft position and vibration by sensing the distance to a conductive target, typically the shaft surface.

Engineered with durability, temperature resistance, and EMI immunity in mind, this proximity probe is ideal for harsh industrial environments. It offers high linearity over a wide range, consistent sensitivity, and strong compatibility with Proximitor® sensors in the 3300 XL system. The model’s long extension length and rugged casing make it suitable for challenging installations in the oil & gas, power generation, and heavy machinery sectors.

Frequently Asked Questions (FAQ)

1. What does the “11 mm” in the probe description refer to?

   It indicates the diameter of the probe tip, allowing greater linear range and durability.

2. Can this probe be used in high-temperature zones near turbines?

   Yes, it supports continuous operation in environments up to 177°C (350°F).

3. Is the cable attached to the probe replaceable?

   The integral cable is not replaceable; however, it can be extended using a Bently Nevada extension cable.

4. What is the function of the ClickLoc® connector?

   It ensures a secure mechanical and electrical connection that resists loosening from vibration.

5. Is this probe suitable for both radial and axial measurements?

   Yes, it can measure both radial vibration and axial thrust movement depending on installation.

6. Can this be used in hazardous areas?

   Yes, when ordered with ATEX/IECEx-certified options, it is suitable for classified zones.

7. What type of target material is required for accurate measurement?

   The probe is calibrated for 4140 steel targets; accuracy may vary with other materials.

8. Is field calibration required after installation?

   Typically no, but periodic validation is recommended during maintenance intervals.

9. Does the probe come with mounting hardware?

   No, mounting brackets or probe holders must be sourced separately or specified at ordering.

10. How does this model compare with a standard 5 mm probe?

    The 11 mm probe provides a longer linear range and is generally used in larger machinery where space allows.
