Measuring device for measuring a thickness of a ferromagnetic metal object

Abstract

The invention relates to a device for measuring a thickness of ferromagnetic metal objects. The measuring device for measuring a thickness of a ferromagnetic metallic object comprises at least two measurement sensors, each of the measurement sensors comprising a core that forms a closed magnetic circuit in combination with at least a part of the ferromagnetic metal object; and a core coil in which a current pulse is formed; wherein the measuring device further comprises a determination unit for determining the time constant of an exponential voltage pulse formed in the coil as a result of forming said current pulse, and an electronic unit which is coupled to each measurement sensor and which controls said sensors.
