Bently Nevada 330105-02-12-15-02-05 3300 XL 8 mm Reverse Mount Proximity Probe

Description

330105-02-12-15-02-05: 3300 XL 8 mm reverse mount proximity probe, configured with 0.2 in unthreaded length (Option 02), 1.2 in case length (Option 12), 1.5 m total system length (Option 15), and miniature click-loc connector (Option 02) with CSA/ATEX/IECEx hazardous area approvals (Option 05). This transducer functions as a non-contact, eddy-current displacement sensor within 3300 XL monitoring chains, providing precise shaft vibration and axial position measurement for critical rotating machinery.

The 330105 reverse mount probe is specifically engineered for installations where the probe is mounted through the machine case from the inside, typically used in housings where access to the rear of the probe is restricted. This component is designed to be compatible with the 3300 XL 8 mm Proximitor sensor and 3300 XL extension cable to maintain the calibrated system accuracy required for turbomachinery protection, fluid-film bearing monitoring, and compressor vibration analysis.

Features

• Reverse mount configuration for inside-case installation
• Option 02: 0.2 in (5.1 mm) unthreaded length
• Option 12: 1.2 in (30.5 mm) case length
• Option 15: 1.5 m (4.9 ft) system length, including probe and extension cable
• Option 02: Miniature ClickLoc connector with standard cable
• Option 05: Agency approvals for CSA, ATEX, and IECEx hazardous areas
• Compatible with 3300 XL 8 mm Proximitor sensor and extension cable systems

Applications

• Turbine-generator vibration monitoring
• Compressor axial position and shaft displacement
• Large centrifugal pump rotor vibration
• Critical rotating machinery protection in oil and gas and power generation facilities

Installation Guidelines

Ensure the probe is installed using the provided locknuts to secure the device within the machine housing. For reverse mount configurations, verify the probe tip has appropriate clearance from the target surface (typically within the linear range of 0.25 mm to 2.3 mm gap). Shielded coaxial cables should be routed away from high-voltage AC lines to prevent signal interference. Observe torque specifications for connector tightening to prevent damage to the ClickLoc mechanism.

Compliance and Certifications

This unit complies with CSA, ATEX, and IECEx hazardous area requirements as specified by Option 05. Ensure site installation meets local safety regulations for the selected classification.
