Abstract

The invention regards a method of incorporating a readable data chip into metallic surfaces for electronic identification. A shock-absorbed data chip is placed in a transverse hole in a cylindrical plug with tight threads, the plug of which is screwed into a ring-shaped plug holder, the internal periphery of which is provided with tight threads. The lower and external periphery is straight and provided with threads, whereas the upper and external periphery is machined into an outwardly directed cone in the region of 30°, and with no threads.Upon mounting, the plug holder is initially screwed into a hole in the pipe wall until the periphery of the cone engages a corresponding cone in the pipe wall. Then the plug is screwed down into the plug holder by means of two mounting holes, the placement of which indicates that the data chip is positioned in the longitudinal direction of the pipe.By removing conductive materials from the regions surrounding the data chip, allows data to be read faster by means of electromagnetic waves generated by an external transmitter/receiver positioned where the data chip is provided with a fixed passing point.Magnetic leakage at the transition between the cone and the threaded portion of the plug holder is transmitted in the surrounding material, and the leakage is directed towards the data chip, too.
