INDUCTIVE ANALYSIS OF METAL OBJECTS

机译:金属物体的归纳分析

摘要

The invention relates to a measuring arrangement and to a method for the inductive analysis of metal objects, comprising a coil arrangement having an excitation coil (1.1) that can be excited by means of an excitation current, and at least one receiver coil (1.2), said two coils being inductively coupled to one another. By means of an evaluation unit, an output signal (5.4) of the measuring arrangement is evaluated. Means for generating a ramp-shaped voltage signal of the excitation voltage (2.5) as a specification for a ramp-shaped current through the excitation coil are provided. A control device regulates the current at the base point of the excitation coil (1.1) such that a ramp-shaped excitation current is produced, which is modulated by the metal object (1.6), and which affects the change in the excitation voltage. Thus, an inductive analysis or detection method is provided, in which temperature influences on the coil system have no effect at all, and which, moreover, allows a spectral analysis of the inductive properties of the metal to be analyzed in a wide frequency range.
