Bently Nevada 86517-01-01-01-02 Proximity Sensor Product Detailed Introduction and Technical Specification
1. Product Introduction
The 86517-01-01-01-02 is a high-precision industrial proximity sensor designed for monitoring the operating condition of rotating machinery.
The product is mainly used for measuring shaft displacement, radial vibration, axial movement, and mechanical position changes in critical rotating equipment. It adopts eddy current non-contact sensing technology, allowing accurate measurement between the sensor probe and the rotating shaft without physical contact.
The non-contact measurement design eliminates mechanical friction between the sensor and the rotating component, improving measurement stability and extending service life. The product is suitable for applications requiring continuous monitoring, high accuracy, and reliable performance.
The 86517-01-01-01-02 is commonly installed on large rotating equipment including turbines, compressors, generators, motors, pumps, and other industrial machines where early detection of mechanical problems is important.
During equipment operation, the sensor continuously measures changes in shaft position and vibration conditions. These signals provide valuable information for machinery protection systems and predictive maintenance programs.
The product helps operators identify possible problems such as rotor imbalance, bearing wear, shaft misalignment, excessive vibration, and abnormal mechanical movement before they develop into serious failures.
The 86517-01-01-01-02 is designed for industrial environments where long operating cycles, high reliability, and accurate measurement performance are required.
