Problems solved by technology
[0004] 1. After the eddy current detector is used for a long time, there is a gap between the data information at the measurement place and the actual detected data, which makes the measurement results inaccurate;
[0005] 2. Since the measurement range of the detector cannot be determined, the fixed value of the detector cannot be determined, and the applicability is poor

Description
technical field [0001] The invention belongs to the technical field of loss detection, and in particular relates to a device for detecting the degree of loss of an eddy current detector. Background technique [0002] Eddy current testing refers to the non-destructive testing method that uses the principle of electromagnetic induction to non-destructively evaluate some properties of conductive materials and their workpieces by measuring the changes of induced eddy currents in the workpiece, or to find defects. In industrial production, eddy current testing is It is one of the main means to control various metal materials and non-metallic conductive materials such as graphite and carbon fiber composite materials and their product quality. It occupies an important position in the field of non-destructive testing technology. A non-destructive testing method, which is suitable for conductive materials; due to changes in various factors of the conductor itself (such as electrical ...
