YK-WL-Series non-contact eddy current displacement sensor is based on the principle that the high-frequency magnetic field forms eddy current effect on the metal surface. It is an ideal sensor to detect and control the displacement, vibration, rotational speed and other mechanical quantities of metal objects. It has the non-contact measurement, wide linear range, high sensitivity, strong anti-jamming capability, no medium effect, stable and reliable, and easy to deal with such obvious advantages, is widely used in metallurgy, chemical industry, aerospace and other industries, can also be used for scientific research and school experiment of displacement, vibration, speed, length, thickness and surface roughness of mechanical testing. In addition, this series of sensors are also widely used in measuring the vibration, axial displacement and speed of rotating shafting system such as steam turbine, compressor and motor, etc., and are widely used in working condition monitoring and fault diagnosis.
