Abstract

The invention discloses an electromagnetic detecting method for the thickness of non-metallic material, a metal plate with finite thickness is lain on the back of the detected surface of the non-metallic material with known thickness, the electromagnetic inductive probe with driving winding coil and testing winding coil is closed to the detected surface, the pumping signal is generated by the driving winding coil, the electromagnetic signal obtained by the testing winding coil is processed to get the data corresponding to the known thickness of the non-metallic material, the thickness model of non-metallic material (includes air) is established, in the actual measurement, the thickness of non-metallic material can be detected with the same method by aid of the model. Using the method, the thickness of non-metallic material with any structure can be detected, and it can reach the measuring goal for the thickness of non-metallic material conveniently, speedily and effectively.

Description

technical field

[0001] The invention relates to a non-metallic material detection method, in particular to a non-metallic material thickness measurement method realized by electromagnetic detection. Background technique

[0002] Non-metallic material is a material with a very wide range of applications. It is widely used in industry, agriculture, infrastructure and our daily life, such as wood, plastic, rubber, etc., which are common in our daily life. These non-metallic materials Metal materials can be made into objects with a certain shape. When it is necessary to know the relevant dimensions of these non-metallic material objects, for example, for the produced plastic board, when it is necessary to know the thickness of the board body, thickness measurement must be performed. The usual thickness measurement method is to use tools such as oil scale calipers or micrometer cards to measure thickness. This method of thickness measurement is not easy to operate, especially dif...
