The Bently Nevada 330104-00-07-50-02-00 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 trusted 3300 XL 8 mm Proximity Transducer System, it delivers consistent signal accuracy, strong environmental resistance, and long operational life in demanding industrial environments.
This configuration includes a 70 mm probe case length (Option 07), a 5.0-meter total system length (Option 50), a standard connector configuration (Option 02), and a standard industrial approval package (Option 00). The extended 5-meter cable makes this model particularly suitable for installations where the probe must be positioned at a greater distance from the monitoring system, such as large turbine halls, compressor stations, or distributed machinery layouts.
It is widely used in turbines, compressors, pumps, motors, and generators, providing continuous real-time vibration data that supports predictive maintenance strategies and improves overall asset reliability.
