Frequently Asked Questions (FAQ)

1. What does the “-92-05” suffix mean in the model 330180-92-05?

   The “-92” indicates a 9.0-meter system length with no mounting hardware, and “-05” signifies compliance with CSA, ATEX, and IECEx hazardous area certifications.

2. Can this sensor be used with high-speed turbines or compressors?

   Yes, it’s specifically designed for high-speed rotating machinery such as steam turbines, compressors, and centrifugal pumps, offering fast and accurate displacement readings.

3. Is the sensor sensitive to electrical noise or interference?

   The 3300 XL 8mm series is engineered with enhanced immunity to EMI and RFI, making it reliable even in electrically noisy environments like motor housings or generator enclosures.

4. What kind of shaft materials can this sensor measure displacement on?

   It is optimized for measurements on AISI 4140 steel (or similar magnetic materials), as required by industry vibration monitoring standards like API 670.

5. Is this product field-replaceable or must it be sent back for service?

   All components—probe, extension cable, and Proximitor sensor—are fully field-replaceable and interchangeable, simplifying maintenance and minimizing downtime.

6. How should the probe be mounted for best performance?

   For accurate readings, the probe should be installed perpendicular to the shaft surface with proper target clearance, using mounting brackets compliant with Bently’s specifications.

7. What type of signal does the sensor output?

   It delivers a linear voltage output (200 mV/mil) proportional to shaft displacement, suitable for direct integration with monitoring systems like the 3500 series.

8. Does it require a specific power supply?

   Yes, it typically requires a -24 VDC power supply within a range of -17.5 VDC to -26 VDC, commonly provided by machinery monitoring systems.

9. Can the sensor be used in hazardous areas?

   Absolutely. The “-05” version is certified for use in hazardous areas under CSA, ATEX, and IECEx guidelines.

10. Can the sensor operate in environments with high moisture or condensation?

    Yes. The housing and sealing meet industrial environmental protection standards. However, proper cable sealing and terminal box use are critical to prevent long-term corrosion.
