ABSTRACT:
The present invention relates to an apparatus for contactless measuring of dimensions of objects, in particular the measurement of the diameter of moving wire in a wire-mill, whereby the contours of the object in one dimension are arranged by means of an optical system to be projected on an opto-electrical member, the output signal of which being a measure of the dimension wanted.
