Abstract: A method for contactlessly determining the temperature of a moving object having an unknown degree of emission, especially a metal wire conveyed along its longitudinal axis, is described: The object is guided through at least one radiation source emitting thermal radiation, wherein the object is mostly or completely surrounded by the at least one radiation source. With at least one radiation detector, a spatially-resolved thermal radiation measurement is performed in a region through which the object passes when it is guided through the radiation source. The temperature of the moving object is determined on the basis of the spatially-resolved thermal radiation measurement. A corresponding device is also described.

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.

Abstract: A method for determining sagging of melt of a tube extruded in an extrusion device includes structuring a measuring device to rotate about the tube. The measuring device is configured to measure a wall thickness of the tube over a circumference of the tube and determine a wall-thickness profile over the circumference of the tube from the measured wall thicknesses. The wall-thickness profile includes a frequency and an amplitude. The method further includes determining a sagging of the melt from at least one of (i) the frequency and (ii) the amplitude of the wall-thickness profile.
