The Bently Nevada 330104-00-08-05-02-05 Proximity Probe Module is a high-reliability non-contact eddy-current sensor designed for continuous measurement of shaft vibration, radial displacement, and axial position in rotating machinery. As part of the established 3300 XL 8 mm Proximity Transducer System, it delivers stable signal performance, strong EMI resistance, and dependable accuracy in demanding industrial environments.
This configuration features an 80 mm probe case length (Option 08), a 0.5-meter system length (Option 05), a standard connector configuration (Option 02), and a hazardous-area certification package (Option 05). It is engineered for compact machinery installations where space is limited but safety compliance is mandatory, such as offshore systems, petrochemical plants, and power generation units operating in explosive-risk zones.
