FAQ

1. What type of sensing technology is used in the 330901-00-08-05-02-RU probe?

   It uses eddy-current non-contact displacement sensing for precise vibration measurement.

2. How does the probe connect to a Bently Nevada monitoring system?

   It connects through a matched extension cable and proximitor driver, maintaining calibration integrity.

3. Can this probe be installed horizontally or vertically?

   Yes, the orientation is flexible as long as the recommended probe-to-shaft gap is maintained.

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

   Typically about 1.0 mm ±0.2 mm, depending on system calibration and target material.

5. Does cable length affect measurement accuracy?

   Yes, the probe and extension cable are factory-calibrated together; changing length requires recalibration.

6. What is the maximum frequency response of the 3300 NSv probe?

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

7. Is the probe compatible with intrinsically safe installations?

   Yes, when used with certified intrinsic safety barriers or approved protective housings.

8. What environmental protection rating does the probe have?

   It carries an IP67 rating, ensuring dust-tight and water-resistant performance.

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

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

10. How is temperature compensation achieved?

    The probe electronics include temperature-compensation circuitry to maintain output stability across its –35 °C to +177 °C range.
