Technical FAQs

1. What is this device used for?

It is a proximitor/preamplifier sensor that processes signals from eddy current proximity probes.

2. What system does it belong to?

It belongs to the Bently Nevada 3300 vibration monitoring system.

3. What does “330100-XX-05” mean?

• 330100: Proximitor sensor family
• XX: configuration placeholder (system length variant)
• 05: agency approvals / compliance variant

4. What is the 9.0 meter reference?

It indicates the system length option (typically 9 m total cable/probe configuration).

5. What is the function in a monitoring chain?

It converts eddy current probe signals into a usable voltage output for monitoring systems.

6. Is it still widely used?

Yes, but mainly in legacy 3300 systems already installed in industrial plants.

7. What industries use it?

Power generation, oil & gas, petrochemical, and heavy manufacturing.

8. Is it interchangeable with newer systems?

Not directly; newer 3300 XL / 3500 systems require matched components.

9. Why is system matching important?

Probe, extension cable, and proximitor must be calibrated as a matched set for accuracy.

10. What is the importance of this module?

It is essential for accurate vibration and shaft position monitoring in rotating machinery.
