Radiation measuring probe for contactless measurement of the surface temperature of an object, independent of the emissivity of the object. The probe includes a radiation receiver and a housing having interior surfaces defining an interior space. The radiation receiver is disposed in the interior space, thermally insulated with respect to the housing. The housing includes a shield which has a shield surface facing outwardly so as to be towards a surface of an object whose surface temperature is to be measured. The shield has an aperture opening into the shield surface, communicating with the interior space and through which thermal radiation emanating from the object impinges on the radiation receiver. The shield surface is blackened and configured to correspond to the contour of the surface of the object, and the interior surfaces of the housing are of low emissivity. A regulatable heating mechanism is provided for regulating the temperature of the housing to correspond to the temperature of the radiation receiver, with the temperature at which correspondence occurs representing the surface temperature of the object. |
