The Bently Nevada 330104-00-05-50-02-RU Proximity Probe Module is a high-reliability eddy-current sensor designed for continuous, non-contact measurement of shaft vibration, displacement, and position in rotating machinery. As part of the widely adopted 3300 XL 8 mm proximity transducer system, it delivers stable signal output, long-term measurement accuracy, and rugged performance in demanding industrial environments.
This configuration includes a 50 mm probe case length (code 05) and a 5.0-meter system length (code 50), making it suitable for large machinery installations where monitoring systems are mounted at a distance. The “02” standard connector configuration provides a universal industrial termination for general-purpose applications. The “-RU” suffix typically indicates a Russia-region commercial or logistics variant, used for regional distribution tracking and compliance while maintaining identical core electrical and mechanical performance to standard global versions.
Designed for turbines, compressors, pumps, and generators, this probe plays a critical role in predictive maintenance systems by detecting early-stage mechanical degradation before failure occurs.
