The Bently Nevada 330104-00-07-50-12-05 Proximity Probe Module is a 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 provides stable measurement performance, strong electromagnetic immunity, 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/cable configuration (Option 12), and a hazardous-area certification package (Option 05). The combination of extended cable reach, reinforced connectivity, and international safety approvals makes it especially suitable for oil & gas, petrochemical, offshore, and power generation facilities where safety compliance is mandatory.
