Bently Nevada 330106-05-30-50-02-05 3300 XL 8 mm Reverse Mount Proximity Probe

Description

The 330106-05-30-50-02-05 is a 3300 XL 8 mm reverse mount proximity probe featuring an M10 x 1 thread, a 50 mm unthreaded length (Option 05), and a 300 mm case length (Option 30). This eddy-current displacement probe is designed for use in 3300 XL 8 mm monitoring chains to provide continuous, non-contact measurement of shaft vibration and axial position in critical rotating machinery.

This configuration utilizes a 5.0 m total system length (Option 50) and includes a miniature coaxial ClickLoc connector with a standard cable (Option 02). The probe is engineered for reverse mount applications, where the probe is installed through the machine case or housing to measure a target (typically a shaft) from the inside. The Option 05 designation certifies this unit for use in hazardous areas with CSA, ATEX, and IECEX approvals.

Installation Guidelines

• Ensure the probe gap is set according to the 3300 XL Proximitor sensor calibration curves.
• Reverse mount probes must be installed using the appropriate jam nuts to secure the position in the machine casing.
• Avoid over-tightening the connector to prevent damage to the ClickLoc mechanism.
• Ensure the extension cable is properly routed and secured to prevent mechanical abrasion or stress.
• For hazardous area installations, adhere to local regulatory requirements for intrinsic safety and equipment protection.

Compliance and Certifications

• CSA, ATEX, IECEX (Hazardous Area Certified per Option 05)
