Product Overview

The Bently Nevada 330705-02-18-90-02-00 is a reverse-mount style proximity probe designed for use within the 3300 XL 8 mm Proximity Transducer System. Reverse mounting supports installations where the probe must be fitted from the backside of a bracket or mounting surface, improving service access in crowded machine housings and reducing maintenance time during inspection or replacement.

As an eddy-current proximity probe, it is used for non-contact measurement of relative shaft displacement. When paired with the correct 3300 XL extension cable and Proximitor sensor of the same system length, the probe supports continuous vibration and position-related measurements used in machinery protection and condition monitoring programs.

Important correction to common listing errors

• This probe is not a “2-wire transmitter” device. Proximity probes in the 3300 XL family operate as part of a probe + cable + Proximitor system; wiring and signal type depend on the Proximitor and monitoring module.

• “Via FEDEX/DHL” is shipping text and not a technical attribute of the product.
