Frequently Asked Questions (FAQ)

1. What is the significance of the 8 mm sensing gap in this proximity probe?

The 8 mm gap allows the probe to detect shaft movement accurately while providing enough clearance to prevent physical contact and sensor damage.

2. How does the probe measure shaft position without contact?

It uses eddy current technology, generating a magnetic field that changes with the distance to the conductive target (shaft), producing a signal proportional to shaft displacement.

3. Can the probe operate in environments with high moisture or dust?

Yes, the probe’s IP67 rating means it is dust-tight and protected against temporary immersion in water, suitable for harsh industrial conditions.

4. Is this probe compatible with other Bently Nevada 3300 series systems?

Yes, it is designed to work seamlessly with 3300 XL monitors and other compatible vibration monitoring systems.

5. What are typical total length options for this probe?

Total cables are 1 meter, but custom lengths are available to meet specific installation requirements.

6. How does temperature affect the probe’s operation?

The probe is rated to operate reliably from -40°C to +120°C, maintaining accuracy across this wide temperature range.

7. What maintenance does the probe require?

Since it operates without physical contact, maintenance is minimal, primarily ensuring connectors and cables are intact and clean.

8. How is the probe mounted on machinery?

The probe features a standard 3/8-24 UNF threaded housing allowing secure, repeatable mounting in probe holders or directly into equipment.

9. What kind of output signal does the probe provide?

It produces an AC variable frequency signal proportional to the distance between the probe tip and the shaft surface.

10. Can this probe be used in explosive environments?

While robust, installation in explosive atmospheres requires compliance with local hazardous area standards and may need additional protective housings or certifications.
