Frequently Asked Questions (FAQ)

1. Does this proximitor sensor require a specific probe type for proper operation?

   It is designed to work with Bently Nevada 3300 XL series proximity probes and matching extension cables for optimal calibration and accuracy.

2. What is the maximum frequency response of the sensor?

   The proximitor supports a frequency response from DC up to 10 kHz, enabling accurate detection of both slow and fast shaft movements.

3. How does the sensor maintain accuracy across wide temperature variations?

   The internal electronics are temperature-compensated and housed in a high-temperature rated enclosure to ensure stable performance from −52 °C to +100 °C.

4. Is the output signal differential or single-ended?

   It provides a differential voltage output, which minimizes susceptibility to electromagnetic interference and maintains signal integrity.

5. Can the sensor be mounted in any orientation without affecting performance?

   Yes, it can be mounted vertically, horizontally, or at an angle as long as the probe-to-target gap is correctly maintained.

6. What level of vibration can this proximitor tolerate during operation?

   It is designed to withstand vibration levels up to 20 g over the 10–2000 Hz frequency range without degradation.

7. Is special shielding required for installation in high-EMI environments?

   No additional shielding is typically required because the sensor features built-in electromagnetic interference protection.

8. How is the proximitor calibrated with the probe and extension cable?

   Calibration is performed as a complete system (probe, cable, and proximitor) to ensure accurate displacement measurements and linearity.

9. Can this proximitor be used in continuous high-humidity environments?

   Yes, it is rated for up to 95% non-condensing humidity and incorporates moisture-resistant components for reliable long-term operation.

10. What kind of power supply does the proximitor require?

    It operates on a standard 24 V DC supply typical of Bently Nevada monitoring systems, ensuring easy integration into existing setups.
