What Is Eddy Currents Effect on Sensors

Eddy currents effect on sensors refers to the phenomenon where a changing magnetic field induces circulating currents in a conductor, which in turn generates a secondary magnetic field that can be measured to determine displacement, velocity, or other physical parameters. According to some sources, eddy current sensors offer high-linearity, high-speed measurements, and high resolution, making them ideal for applications such as shaft displacement measurement in rotating machinery. Reportedly, they are used in various industries, including industrial automation, aerospace engineering, and medical imaging.
