Bently Nevada 330101-00-45-20-12-05 3300 XL 8 mm Proximity Probe

Description

The 330101-00-45-20-12-05 3300 XL 8 mm proximity probe features a 3/8-24 UNF threaded body, designed for non-contact eddy-current displacement measurement in 3300 XL monitoring chains. This configuration includes 0.0 in unthreaded length (Option 00), a 4.5 in case length (Option 45), and a 2.0 m total system length (Option 20). It is equipped with a FluidLoc cable and miniature coaxial ClickLoc connector (Option 12), ensuring reliable connectivity, and holds CSA, ATEX, and IECEx hazardous area approvals (Option 05).

The 3300 XL 8 mm proximity probe system is the standard for critical rotating machinery protection, providing accurate shaft vibration and position measurement. The FluidLoc cable construction (Option 12) prevents oil and other liquids from leaking through the cable jacket, making this specific variant suitable for environments where fluid sealing integrity is a primary requirement. This probe pairs with the 3300 XL Proximitor sensor and extension cable to form a complete calibrated measurement chain.

Installation Guidelines

Ensure the probe is gapped correctly according to the 3300 XL 8 mm transducer system manual using the standard calibration curve. Protect connectors using connector protectors (such as 40180-02) to prevent contamination. Ensure the FluidLoc cable is routed to maintain seal integrity. Secure the probe using appropriate brackets, such as the aluminum threaded mounting bracket (137492-AA) or phenolic bracket (27474-AA) for electrical isolation where required. Avoid overtightening mounting hardware to prevent mechanical stress on the probe body.
