Produkteinführung
The Bently Nevada 330703-050-120-10-02-00 3300 XL 11 mm Proximity Probe is an advanced non-contact vibration and displacement sensor designed for precision monitoring von rotating machinery such as turbines, compressors, pumps, and motors. It belongs to the 3300 XL series, a globally recognized standard for machinery protection and condition monitoring systems developed by Bently Nevada.
This proximity probe functions based on eddy current sensing technology, where the probe generates an electromagnetic field and detects changes caused by the movement von a conductive target, typically a rotating shaft. The resulting voltage output is directly proportional to the target’s displacement or vibration amplitude, providing real-time data for machinery condition assessment.
The 330703-050-120-10-02-00 model delivers exceptional accuracy and stability, even under extreme industrial environments characterized by high temperature, oil contamination, and electrical interference. When used together with the 3300 XL Proximitor Sensor and compatible extension cables, it forms a complete transducer system compliant with API 670 standards, ensuring reliable and repeatable measurements for both static and dynamic shaft position monitoring.
This probe’s design emphasizes long-term stability, corrosion resistance, and superior linearity. It represents a critical component for predictive maintenance systems in power generation, oil and gas, and heavy machinery industries.
