The Bently Nevada 330104-00-07-90-12-00 Proximity Probe Module is a high-precision non-contact eddy-current sensor designed for continuous monitoring of shaft vibration, radial displacement, and axial position in rotating machinery. As part of the proven 3300 XL 8 mm Proximity Transducer System, it delivers stable signal performance, strong electromagnetic immunity, and reliable long-distance measurement capability for demanding industrial environments.
This configuration includes a 70 mm probe case length (Option 07), an ultra-extended 9.0-meter total system length (Option 90), a standard connector configuration (Option 02), and a special connector/cable design (Option 12). The Option 12 variant typically uses a miniature coaxial ClickLoc connector with FluidLoc-style cable construction, improving sealing reliability and installation stability in complex machinery layouts.
It is widely used in turbines, compressors, pumps, generators, and heavy rotating machinery where long-distance signal routing and stable vibration monitoring are essential for predictive maintenance and operational safety.
