Frequently Asked Questions (FAQ)

1. What is the typical sensing distance for this probe?

   The typical gap between the probe tip and the target shaft surface is about 8 mm, with a measurement range of ±2 mm for vibration.

2. Can this probe be used in explosive environments?

   Yes, when paired with the appropriate intrinsic safety barriers and certified monitoring systems, it can be used in hazardous locations.

3. What type of output signal does the probe produce?

   It produces an AC voltage output proportional to the distance between the probe tip and the rotating shaft.

4. How long is the standard cable length?

   The standard cable length is 2 meters but can be customized upon request.

5. What maintenance is required for the probe?

   The probe requires minimal maintenance; periodic visual inspections and cleaning of the tip are recommended.

6. Is the probe compatible with other manufacturers’ monitoring systems?

   It is primarily designed for Bently Nevada 3300 XL systems but may work with other systems supporting eddy-current proximity probes.

7. What is the operating temperature range of the probe?

   The probe operates reliably between -40°C and +120°C.

8. How resistant is the probe to vibration and shock?
