Bently Nevada 330106-05-30-90-02-05 3300 XL Reverse Mount Proximity Probe

Description

The Bently Nevada 330106-05-30-90-02-05 is a 3300 XL 8 mm eddy-current proximity probe configured for metric reverse-mount installations (M10 x 1 threads). Unlike standard forward-mount probes, this model threads into a mounting sleeve from the rear, making it ideal for applications with limited external access.

This configuration features a 5.0 mm unthreaded tip length, a 30 mm overall case length, and an integrated 9.0-meter (29.5-foot) coaxial cable. The 9.0 m total length allows for a direct connection to a 9.0 m Proximitor® sensor without an intermediate extension cable, reducing connection points in confined areas. The unarmored standard cable terminates in a gold-plated miniature male ClickLoc™ coaxial connector and includes Option 05 hazardous area approvals for international compliance.

Features

• 8.0 mm eddy-current sensor tip calibrated for non-contact displacement and dynamic vibration measurements.
• Reverse-mount design threads directly into a mounting sleeve from the back end.
• M10 x 1 threaded stainless steel body with a 5.0 mm unthreaded tip and 30 mm case length.
• Integrated 9.0-meter (29.5 ft) standard coaxial cable eliminates the need for a separate extension cable.
• Gold-plated ClickLoc™ coaxial connector locks firmly without specialized tools.
• Unarmored cable construction, optimized for routing inside protective field conduits.
• Option 05 agency approvals cover CSA, ATEX, and IECEx hazardous area regulations.
• Fully compatible with standard 3300 XL Proximitor® sensors (330180 series).

Applications

• Radial shaft vibration and rotor dynamics analysis on fluid-film bearing machinery.
• Thrust and axial shaft displacement monitoring on high-speed turbines, compressors, and pumps.
• Keyphasor® speed and phase reference measurements on rotating elements.
• Shaft motion and runout monitoring on hydroelectric generators.
• API 670 machinery protection systems within power generation and petrochemical processing plants.

Installation Guidelines

• Install the probe by threading it into the rear of a Bently Nevada mounting sleeve or custom adapter block.
• Verify thread depth; do not exceed 15 mm of thread engagement length to prevent mechanical binding.
• Maintain a minimum probe-to-probe separation distance (at least 40 mm for axial sensors, 38 mm for radial sensors) to prevent cross-talk interference.
• Hand-tighten ClickLoc™ connectors until an audible click is achieved; do not use pliers or excessive torque.
• Route standard, non-armored cables through protective metal conduit to safeguard against mechanical wear or environmental damage.
