FAQ

1. What sensing technology is used in this probe?
   The probe uses eddy current technology to measure shaft displacement and vibration without physical contact.

2. Can this probe integrate with standard Bently Nevada monitoring systems?
   Yes, it is fully compatible with 3300 NSv drivers and other Bently Nevada monitoring equipment.

3. What is the typical measurement linearity?
   The probe provides ±1% full-scale linearity for high measurement accuracy.

4. Does it support high-speed machinery monitoring?
   Absolutely, its 0–10 kHz frequency response makes it ideal for high-speed turbines, compressors, and motors.

5. How is the probe mounted?
   It can be installed using threaded or flanged fittings depending on equipment requirements.

6. What type of signal cable is recommended?
   A shielded low-noise coaxial cable is recommended to maintain signal integrity and reduce interference.

7. Can it operate reliably in extreme temperature environments?
   Yes, the probe is designed for operation from –40 °C to +125 °C.

8. Is regular recalibration necessary?
   After initial setup with its driver, the probe generally maintains calibration for extended periods without frequent adjustments.

9. How does it handle industrial contaminants such as oil or dust?
   Its stainless-steel sealed housing provides strong resistance to oil, dust, and moisture.

10. Can it detect rotor imbalance or misalignment indirectly?
    Yes, by continuously tracking shaft displacement and vibration, the probe provides data that helps identify imbalance or misalignment early.
