Cutting-edge technologies in modern science and technology are an important indicator of a country's technological development level. There are various types of displacement sensors on the market; for example, eddy current displacement sensors are widely used in various industries. So, what are the advantages of eddy current displacement sensors?
1. Eddy current displacement sensors can measure the relative position of the measured object (which must be a metal conductor) and the probe end face.
2. Eddy current displacement sensors have high reliability, high sensitivity, strong anti-interference ability, non-contact measurement, fast response speed, and are not affected by media such as oil and water. They are often used for long-term real-time monitoring of parameters such as shaft displacement, shaft vibration, and shaft speed of large rotating machinery. They can analyze the working status of the equipment and the cause of failure, effectively protect the equipment and perform predictive maintenance.
3. From the theoretical analysis of rotor dynamics and bearing science, the operating state of large rotating machinery mainly depends on its core—the shaft. Eddy current displacement sensors can directly measure the state of the shaft, and the measurement results are reliable and trustworthy. In the past, vibration measurement of machinery used acceleration or velocity sensors, which indirectly measured shaft vibration by measuring casing vibration, resulting in low reliability of the measurement results.
