    摘要： A method and apparatus for measuring temperature by making use of a state change of a working fluid. The temperature measurement is executed in a manner that the working fluid is initially supplied at a constant mass flow rate into a flow channel thereof defining a throttle portion at a temperature-sensitive portion and upon measurement of a pressure difference between opposite ends of the throttle portion, the temperature can be recognized through calculation of the measured pressure difference. The temperature measuring apparatus includes a source of supply of a working fluid, a probe having an external cylinder closed at its one end and an internal cylinder which is accommodated in the external cylinder and has a capillary tube at its forward end, a supply tube of the working fluid for introducing the working fluid from the source thereof into either the internal cylinder or the external cylinder, a pressure control device and a mass flow control device disposed in series in the course of the supply tube, a differential pressure gauge for detecting a pressure drop across the capillary tube, and a temperature operating device for operating the temperature on the basis of a signal sent from the differential pressure gauge.

    摘要： Ein Kühl- oder Gefriergerät mit mindestens einem Lagerfach für Kühl- oder Gefriergut ist mit einem die Temperatur in dem Lagerfach messenden Thermometer versehen. Um bei einfachem und stabilem Aufbau eine hohe Anzeigegenauigkeit und einfache Ablesbarkeit des Thermometers bei hoher Trägheit zu erreichen, ist das Thermometer ein Galilei-Thermometer mit mindestens einem Schwebekörper. Die in einem transparentem Behälter eingeschlossene Flüssigkeit und die in dieser schwebende Kugel oder der Schwebekörper sind auf eine vorbestimmte Temperatur geeicht.
