The Bently Nevada 330901-00-08-10-02-RU 3300 NSv Proximity Probe is a precision non-contact sensor engineered for small, high-speed rotating machinery where installation space is limited but measurement accuracy is critical. Part of the trusted 3300 NSv (Narrow Side-view) series, it delivers continuous, real-time monitoring of shaft vibration and radial/axial position. Its robust stainless-steel construction, compact tip, and factory-matched cable make it ideal for harsh industrial environments such as petrochemical plants, power generation facilities, and high-speed compressors. Designed for seamless integration with Bently Nevada 3300 and 3500 monitoring systems, this probe supports predictive maintenance programs and helps prevent costly machinery failures.

FAQ

1. What sensing technology does the 330901-00-08-10-02-RU use?

   It employs eddy-current non-contact displacement sensing for accurate vibration monitoring.

2. How is the probe connected to a Bently Nevada system?

   Through a factory-matched extension cable and proximitor driver, ensuring precise calibration.

3. Can the probe be mounted in any orientation?

   Yes, horizontal or vertical mounting is acceptable as long as the recommended gap is maintained.

4. What is the recommended probe-to-shaft gap?

   Approximately 1.0 mm ±0.2 mm, depending on target material and system configuration.

5. Is the probe compatible with intrinsically safe installations?

   Yes, when used with certified intrinsically safe barriers or approved protective enclosures.

6. Does the 1.0 m cable length affect calibration?

   No, the probe and cable are factory calibrated as a set; do not alter length without recalibration.

7. What is the maximum frequency response supported?

   The probe provides a flat response from DC up to approximately 10 kHz.

8. Can it detect vibration on non-metallic shafts?

   No, it requires a conductive metallic target for eddy-current sensing.

9. How is temperature-induced drift minimized?

   Built-in temperature compensation ensures stable output across its full operating range.

10. What environmental protection rating does the probe carry?

    It meets IP67, offering dust-tight and water-resistant performance.
