Frequently Asked Questions

1. What is this probe used for?

It measures shaft vibration, shaft position, eccentricity, and rotational reference on fluid-film bearing machinery.

2. What does the "30" option indicate?

It specifies a 3.0-inch unthreaded probe length.

3. What does the "60" option indicate?

It specifies a 6.0-inch overall probe case length according to the 3300 XL ordering configuration.

4. What cable length does this model include?

The 90 option specifies a 9.0-meter (29.5-foot) integral cable.

5. What connector is fitted?

The 02 option specifies a Miniature coaxial ClickLoc® connector with a standard cable.

6. What does the "CN" approval option mean?

The CN version includes China-specific product approvals and associated certification documentation for installations requiring Chinese regulatory compliance.

7. Which Proximitor® Sensor should be used?

Because this probe has a 9-meter integral cable, it should be paired with the corresponding 9-meter 3300 XL Proximitor® Sensor configuration for proper system performance.

8. Is it API 670 compliant?

Yes. When installed as part of a complete 3300 XL 8 mm Proximity Transducer System, it is designed to meet API 670 requirements.

9. Can it replace another 3300 XL probe?

Yes, provided the replacement matches the required mechanical dimensions, cable length, connector configuration, and overall transducer system length.

10. What are the main benefits?

It offers highly accurate, stable, non-contact shaft measurements with excellent long-term reliability for machinery protection, condition monitoring, and predictive maintenance.
