The Bently Nevada 330104-00-05-50-02-00 Proximity Probe Module is a high-precision eddy-current sensor designed for continuous, non-contact measurement of shaft vibration, displacement, and position in mission-critical rotating machinery. As part of the industry-proven 3300 XL 8 mm proximity transducer system, this probe delivers strong measurement stability, excellent linearity, and long-term reliability in harsh industrial environments.
This configuration includes a 50 mm probe case length (code 05) and a 5.0-meter system cable length (code 50), making it particularly suitable for installations where the monitoring system is located at a significant distance from the machinery. The “02” standard connector configuration provides a cost-effective and widely compatible termination option for general industrial applications. The design is widely used in turbines, compressors, pumps, and generators across power generation, oil & gas, and petrochemical industries.
With its non-contact eddy-current measurement principle, the probe enables early detection of mechanical issues such as imbalance, misalignment, shaft rub, and bearing wear—supporting predictive maintenance strategies and improving overall equipment reliability.
