摘要

Method for measuring different parameters of conditions in electrically conductive material, and device for implementing the method. It is described a method for measuring the parameters of ferromagnetic steel structures, for example, rails and rail drill strings to detect mechanical stress, damage or deterioration.In the monitored area, devices for magnetizu00e7u00e3o or degaussing, for example, an electromagnet is installed according to the need. Are provided with two or more electrodes for power supply, by means of which an electric voltage in the form of a pulse is applied. Another pair of electrodes, a signal voltage response is measured.This response signal is compared with a signal measured in the measuring conditions are known, or is compared with calibration data for the object. The difference between these voltages is analyzed to quantify the relative or absolute deviations and, on this basis, the condition of the steel structure is estimated.The device can measure the curves of transient voltage with reference to one or more of the curves of magnetization, and includes algorithms to analyze the response curve of voltage for determination of mechanical stress and / or fatigue and / or cracks and / or loss of metal in steel materials.
