    1348955 Measuring resistance NUKLEARMESSTECHNIK UND INDUSTRIEELEKTRONIK M KNUFELMANN & CO mbH GES FUR 28 March 1972 [14 April 1971] 14436/72 Heading G1U The resistance per unit length at a predetermined temperature of a continuouslymoving conductor L is determined by simultaneously measuring the resistance and temperature of the conductor at short intervals of time, and calculating from these measurements (e.g. by computer) the resistance at the predetermined temperature. The measuring arrangement comprises current contacts 1 and voltage contacts 2 pneumatically or magnetically pressed (3) against the conductor, and a radiation thermometer 4, 5, all carried by a moving carriage (not shown) associated with a return device so that the measuring arrangement can follow the movement of the conductor.

    (54) DEVICE FOR MEASURING ELECTRICAL RESISTANCE The invention relates to a device for measuring with temperature correction the electrical resistance of an extended conductor that is in production. The measurements are carried out on a direct current using the four-electrode method, with the galvanometer and the measuring bridge being the measuring instruments. When measuring the resistance of a conductor with known devices, the production process of this conductor is interrupted. When the conductor is stationary, two current contacts are pressed in to supply the test current. At the section over which the current flows, two contacts of voltage are simultaneously located, for example, at a distance of 1 M from each other. The voltage contacts are connected to a suitable voltage measuring device, so that with a known current, the ohmic resistance of the conductor can be calculated. After the measurement, the contacts from the conductor are removed and the manufacturing process is continued. CONDUCTOR Since during the measurement the temperature of the conductor must be known, during the measurement the conductor is immersed in a medium with a constant temperature, such as a water bath. The disadvantage of such a device is that the production process when measuring its resistance must be interrupted. In many cases, it is necessary to control the resistance of the conductor, for example, to narrow the pre-fabrication of the workpiece, for short periods of time between measurements (because it is not economically profitable to interrupt the production process. The purpose of the invention is to increase the resistance measurement speed and temperature in a continuous production process. For this purpose, current and potential contacts (probes) are placed in a longitudinal moving conductor. They are located on the longitudinal axis of the conductor and have V or U-o a different shape, thereby making it possible to better contact. In this case the resistance value continuously moving conductor of
