Abstract
Abstract A rapidly responding, electric thermometer for measuring surface temperatures is described which permits only a minimum heat transfer of temperature. The thermometer consists of a housing open at the bottom in which, ending with the lower edge of the housing, a temperature sensor is embedded by means of a poorly heat conducting material. The heat transfer between the lower part of the housing and the upper part of the housing is suppressed to a great extend with several radial slits in the housing which allow only two or more bridges to remain standing.
