Abstract
A method for measuring a tubular strand exiting from an extrusion device comprises directing electromagnetic radiation from an inside of the tubular strand to an inner side of a tubular strand. The electromagnet radiation is radiated from at least one radiation source within a frequency range from 1 GHz to 6000 GHz. The electromagnetic radiation is reflected off of the tubular strand and received by at least one radiation receiver. A value for at least one of a diameter, a wall thickness, and a deviation in shape of the tubular strand is determined from the electromagnetic radiation received by at least one radiation receiver.
