The Bently Nevada 330104-00-07-90-02-05 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 industry-proven 3300 XL 8 mm Proximity Transducer System, it delivers stable measurement performance, strong noise immunity, and dependable long-distance signal transmission in 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 hazardous-area certification package (Option 05). It is specifically engineered for large-scale industrial installations where equipment is widely distributed and compliance with explosive-atmosphere safety standards is required, such as oil & gas, offshore platforms, petrochemical complexes, and power generation facilities.
