The Bently Nevada 330104-00-04-10-02-CN Proximity Probe Module is a high-precision non-contact eddy-current sensor designed for continuous monitoring of shaft vibration, displacement, and position in critical rotating machinery. As part of the globally recognized 3300 XL 8 mm proximity transducer system, this model delivers reliable measurement accuracy, long-term stability, and robust performance in demanding industrial environments.
This configuration features a 40 mm probe case length (code 04) and a 1.0-meter system length (code 10), making it suitable for medium-distance installations where flexible routing between machinery and monitoring systems is required. The “02” standard connector configuration provides a cost-effective and widely compatible termination option for general industrial applications. The added “-CN” suffix typically indicates a China-region commercial or distribution variant, often used for localized supply chain compliance and regional inventory tracking while maintaining identical core technical performance.
Engineered for turbines, compressors, pumps, motors, and generators, this probe supports predictive maintenance strategies by enabling early detection of mechanical issues before they escalate into equipment failure.
