Bently Nevada 330103-00-06-05-02-00 3300 XL Proximity Probe

Product Overview

The 330103-00-06-05-02-00 from Bently Nevada is a precision 3300 XL 8 mm eddy-current proximity probe engineered for continuous vibration and shaft-position monitoring on critical rotating equipment. Designed for long-term industrial operation, this probe delivers stable, repeatable measurements under demanding mechanical and thermal conditions.

As a core component of the 3300 XL Proximity Transducer System, the probe operates together with a matched extension cable and Proximitor® sensor to produce an analog voltage signal proportional to the distance between the probe tip and the rotating surface. This enables accurate static position and dynamic vibration analysis in machinery protection systems.

System Compatibility

The 330103-00-06-05-02-00 is intended for use within a complete 3300 XL 8 mm system, consisting of:

FAQ

Can this probe be used without a matching Proximitor® sensor?

No. Accurate measurement and linear performance require a properly matched 3300 XL extension cable and Proximitor® sensor.

Is this probe suitable for API 670 systems?

Yes. When used in a standard 3300 XL 8 mm configuration, the system complies with API 670 requirements.

What is the difference between 330103 and other 3300 XL probe models?

The primary differences are case length, cable length, and connector configuration. The sensing performance remains consistent across the 3300 XL 8 mm probe family when properly matched.
