Eddy current sensor is a sensor used to detect whether there are defects on the surface of metal objects or to measure the characteristics of metal objects. It is based on the principle of electromagnetic induction and detects changes in eddy currents to identify and measure the characteristics of target objects. Here are some examples of practical applications for eddy current sensors:
1. Non-destructive testing: Eddy current sensors are widely used in the field of non-destructive testing, such as detecting defects such as cracks, pits, corrosion, coating thickness, etc. on metal surfaces, as well as the integrity and quality control of metal parts.
2. Abnormal detection: Eddy current sensors are often used to detect foreign objects, debris or abnormal conditions in rotating machinery, such as detecting foreign object intrusion in aircraft engines, metal particles in automobile engines, bearing damage, etc.
3. Metal sorting: Eddy current sensors can be used to sort and recycle metal waste, and classify and separate metal objects according to different conductivity or magnetic permeability characteristics.
4. Material measurement: By measuring the intensity and frequency changes of eddy current, the eddy current sensor can measure the conductivity, magnetic permeability, hysteresis loss and other characteristics of metal materials.
5. Suspension system control: Eddy current sensors are often used for the control and feedback of suspension systems, such as height adjustment of automobile suspension systems, load detection of elevators, etc.
Generally speaking, eddy current sensors have a wide range of practical applications in industry, manufacturing, aerospace, automobiles, railways, construction, and energy. They provide a precise, efficient and reliable method to detect the characteristics and defects of metal objects, improving production efficiency and quality control.
