MAGNETIC FLAW DETECTOR FOR DIAGNOSTICS OF UNDERGROUND STEEL PIPELINES

摘要

The device relates to measuring technology and more particularly to means for the contactless diagnostics of underground steel pipelines. The technical result of the invention is an increase in measuring accuracy. The device comprises a housing in which are arranged at least two magnetoresistive magnetic field sensors positioned at different heights in the housing and each comprising three magnetic field transducers disposed along coordinate axes X, Y and Z, and at least two amplifiers which are connected to the corresponding sensors and to an input of an analogue-to-digital converter which is connected to the input of a unit for wirelessly transmitting data, which is capable of transmitting magnometric data to a tablet field computer having a georeferencing unit connected thereto.
