Introduction — Extended-Configuration Precision for High-Demand Machinery Monitoring
The Bently Nevada 330103-00-13-10-12-00 3300 XL 8mm Proximity Probe is a high-performance eddy-current sensor designed for continuous shaft vibration and position measurement in critical rotating machinery. As part of the industry-proven 3300 XL 8mm proximity transducer system, it delivers stable, drift-resistant performance in turbines, compressors, pumps, and generators operating under demanding industrial conditions.
The “13” configuration typically indicates an extended case design, while the “12” cable/connector variant provides flexible installation routing for distributed monitoring architectures. This makes it suitable for complex plant layouts where mechanical access and wiring paths require additional adaptability.
