Abstract (en)

[origin: DE19829999C1] The invention relates to a method and measuring device for detecting the proper insertion depth in a pipe press-fitted connection comprising an eddy current device, a probe connected thereto, and a measuring circuit. Said measuring circuit is provided in the eddy current device and evaluates eddy current signals in such a way that a signal is produced according to the proper or improper insertion depth. For this, the probe (8) is dimensionally configured such that it can also be placed using the same application pressure on the smallest nominal dimension to be measured of a press fitting (1) or of a press fitting element without interfering with the measured result. After inserting the end area of the pipe in the press fitting or in the press fitting element, eddy current of a suitable frequency is passed into the connection in the overlapping area between the pipe and the press fitting, and the receiving signal is transformed into a good-bad indication, whereby the insertion area which can be detected from the exterior forms the point of incidence of the current.
