The Bently Nevada 330104-00-07-50-12-00 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 widely adopted 3300 XL 8 mm Proximity Transducer System, it delivers stable signal output, strong EMI resistance, and long-term reliability in demanding industrial environments.
This configuration features a 70 mm probe case length (Option 07), a 5.0-meter total system length (Option 50), a special connector and cable configuration (Option 12), and a standard industrial approval package (Option 00). The Option 12 design typically uses a miniature coaxial ClickLoc connector with FluidLoc-style cable construction, improving sealing performance and connection stability in challenging installations.
It is commonly applied in turbines, compressors, pumps, generators, and heavy rotating equipment where extended cable routing and high installation flexibility are required.
