Abstract
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.
