The Bently Nevada 330104-00-07-90-02-00 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 provides stable signal performance, strong environmental robustness, and reliable long-distance measurement capability for complex industrial installations.
This configuration includes a 70 mm probe case length (Option 07), an extremely extended 9.0-meter total system length (Option 90), a standard connector and cable configuration (Option 02), and a standard industrial approval package (Option 00). The standout feature of this model is its ultra-long cable length, making it suitable for large turbine halls, distributed compressor systems, offshore platforms, and installations where monitoring equipment must be placed far from the measurement point.
