Bently Nevada 330105-02-12-10-02-05 3300 XL 8 mm Reverse Mount Proximity Probe

Description

The 330105-02-12-10-02-05 is a 3300 XL 8 mm reverse mount proximity probe, designed for non-contact eddy-current displacement measurement within 3300 XL monitoring systems. This configuration features a 3/8-24 UNF thread, an unthreaded length of 20 mm (Option 02), a total case length of 120 mm (Option 12), and a 1.0 meter total system length (Option 10). It is equipped with a miniature coaxial ClickLoc connector and standard cable (Option 02) and is certified with CSA, ATEX, and IECEx approvals (Option 05).

Reverse mount probes are primarily used in applications where the probe must be mounted from the inside of the machine case, facing outward. This transducer system provides highly accurate shaft vibration and axial position measurements in critical rotating machinery, including steam and gas turbines, compressors, and pumps. It is fully compatible with 3300 XL Proximitor sensors and extension cables, ensuring linear, reliable signal transmission across the specified measurement range.

Installation Guidelines

Ensure that the probe is installed with the correct gap distance as specified in the 3300 XL system manual. The probe must be mounted to a rigid surface to prevent false vibration readings. When installing in hazardous areas, ensure that all local wiring regulations and the specific agency approvals (Option 05) are strictly followed. Do not subject the probe tip to excessive force or impact during installation. Maintain proper shielding and grounding practices for all field wiring to minimize electromagnetic interference.
