The Bently Nevada 330101-25-44-10-02-05 is a high-performance 3300 XL 8 mm Proximity Probe engineered for continuous vibration and shaft position monitoring in rotating machinery. As part of the renowned 3300 XL 8 mm Proximity Transducer System, this probe delivers accurate non-contact measurements for critical assets including steam turbines, gas turbines, compressors, pumps, motors, generators, and other industrial rotating equipment.

The probe also offers backward compatibility with many legacy 3300 Series 5 mm and 8 mm transducer system components, providing a practical upgrade path for existing installations. In applications where installation space is limited, the broader 3300 family also supports 5 mm probes while maintaining compatibility with the monitoring system, giving engineers greater flexibility when designing or upgrading machinery protection systems.

Frequently Asked Questions

Q : What is the diameter of the 330101-25-44-10-02-05 probe tip?

A : The probe tip has a nominal diameter of 8 mm.

Q : What thread type does this 330101-25-44-10-02-05probe use?

A : It uses an English thread size of 3/8-24 UNF.

Q : Is the cable on this part number armored or unarmored?

A : The -02 option designates a standard unarmored cable with a ClickLoc coaxial connector.

Q : Can I connect this 1.0-meter probe directly to a monitor rack?

A : No. This probe must be connected to a matching 3300 XL Proximitor Sensor via a dedicated Extension Cable.
