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

Description

The 330105-02-12-05-02-05 is a 3300 XL 8 mm reverse mount proximity probe designed for critical machinery vibration and axial position monitoring. This configuration features a 3/8-24 UNF thread, a 1.2 inch case length, and a 0.5 meter total length with a standard miniature ClickLoc connector. Certified with Option 05 (CSA, ATEX, IECEx), this probe is suitable for hazardous area installations where reliable non-contact displacement measurement is required for sleeve-bearing or fluid-film bearing machinery.

Reverse mount probes like the 330105 are specifically engineered for applications where the probe must be installed through the machine case or housing, requiring the cable to exit through the rear of the probe body. The 3300 XL system, comprising this probe, a 330180 Proximitor sensor, and a 330130 extension cable, provides high-accuracy, linear output for monitoring shaft vibration and position in industrial rotating equipment such as steam turbines, gas compressors, and large centrifugal pumps.

Features

• Reverse mount configuration for through-case installation
• 3/8-24 UNF-2A thread for standardized machine mounting

Installation Guidelines

Ensure the probe is installed in accordance with Bently Nevada installation drawings for the specific hazardous area classification (e.g., 141092 for ia). When mounting in hazardous locations, ensure the Proximitor sensor provides terminals with at least IP54 protection. Reverse mount probes should be tightened securely through the machine housing, ensuring that the unthreaded length and probe gap are correctly set to maintain linear measurement accuracy.

Compliance and Certifications

• CSA, ATEX, IECEx approved for hazardous locations (Option 05)
