    The invention relates to a method of and an apparatus for measuring surface temperature of especially moving objects, advantageously measuring the temperature of fibrous products, and particularly of wires during production. The essence of the method lies in that two concentric shells not being contiguous with either the object to be measured or with one another are fitted to the object to be measured, temperature is sensed in the two end locations and in the central region of the inner shell, and in the central region of the outer shell, these values are brought to be equal to the value measured in the central region of the inner shell by dissipation or by heat transfer (heating), then temperature is measured in the central region of the inner shell. The essence of the apparatus lies in that it comprises two concentric shells separated from one another, an inner sensing and an outer compensating shell, being provided with heated surfaces, and dissipating elements, respectively. The method and the apparatus according to the invention are suitable for measuring surface temperature of moving elements, particularly of wires, fibres, strips moving at a speed of 0 to 65 m/s, irrespective of surface quality, material, or relatively low temperature ranges, where temperature radiation is hard to measure.

    shell. The inner surface of the inner shell 2 does not have contact with the outer surface of the object being measured. The inner shell 2, as well as the outer shell 3, consists of two parts aligned with each other along the longitudinal axis, which allows for the dismantling of the shells even if a measured object is inside them.
    The inner 2 and outer 3 shells are preferably cylindrical, but it is possible to use other shapes consistent with the shape of the object being measured. Heat transfer elements 4 and 7 can be replaced with heat dissipation if necessary. The outer shell 3 is installed shell 2, em in the longitudinal direction of the form, symmetrical to the inner shell 2.
    In the case of measuring the temperature of the wire and fibers, the two heat supply elements 4 of the inner sheath and two sensors 5 of the temperature of the inner sheath are connected to a common outlet. In other cases, connecting with
    general conclusion is not necessary.

    The device works as follows.
    By means of the guiding element I, inner 2 and outer 3 shells are mounted on the object to be measured coaxially with it. Temperature sensors 5,6 and 8 measure the temperature in the end zones of the inner
    apart from the inner concentric with it and having
    The middle zone of the outer shell of the adjacent 4 shell 2, in the middle zone is internal to the input of the regulator 11, the output of which is connected to the input of the power amplifier 12, which is connected to the heat supply element 7 of the outer shell. A sensor 5 for the temperature of the end zone of the inner surface is connected to the input of the regulator 13 whose output is connected to the input of the power amplifier 14 connected to the heat supplying element 4 of the inner shell.
    The guide element 1 is made of two parts with an inner diameter smaller than the diameter of the inner shell 2, provides the location of the measured object (not shown) strictly along the axis of the shell and reduces the amount of air entering the inner cavity of the inner
    shells in the middle zone of the outer shell 3. If the temperatures are different, they are regulated by heat transfer. For example,
    The signal from the temperature sensor 5 of the end zone of the inner surface is fed to the regulator 13 n and then to the power amplifier 14, which provides recharge of the heat supply element 4 of the inner shell. Similarly, the signal from the temperature sensor 8 of the middle zone of the outer shell 8 is fed to the controller 11, then to the power amplifier 12, which provides the heat supply element 7 of the outer shell. By adjusting the heat transfer, it provides the same readings of the temperature sensors 5.6 and 8. At the moment when the temperatures are the same, the temperature in the middle zone of the inner shell is determined using the temperature sensor 6, the signal from which after amplifier 9 goes to analog indicator 15 and further on analog digital converter 16. The surface temperature of moving objects is equal to the temperature measured by the temperature sensor of the middle zone of the inner shell.
