The flat steel wire is a metal product which is cold-processed to a designed size by adopting metal materials such as high-quality carbon steel, alloy steel, stainless steel and the like through rolling, die drawing, roll drawing and the like. The flat steel wire has the characteristics of good mechanical property, high dimensional precision, excellent surface smoothness and the like, and is widely applied to the fields of automobiles, household appliances, medical treatment, daily supplies and the like.

In the process of processing and forming the flat steel wire, the stress state is complex, so that in order to ensure the outer diameter size precision of the flat steel wire, the real-time measurement and monitoring of the outer diameter of the flat steel wire in the production process are very important. At present, optical diameter measuring equipment such as infrared or laser is installed on a production line by some manufacturers to measure the outer diameter of the flat wire on line in real time, but the measurement precision cannot be guaranteed due to the influences of factors such as vibration of mechanical equipment for producing the flat steel wire, slight overturn of the flat wire, shaking and the like. Especially, the thickness of flat steel wire is littleer for width size, and because of the side blocks the light influence during the shake upset, the measuring accuracy of optics caliber is unable to obtain guaranteeing more.
