Abstract
A sensor for measuring the temperature of a liquid or semi-solid material by electrical heating. A core rod has disposed thereon a first electrically insulating member and a thin metal wire is wound about the first insulating member on the core rod. A second electrically insulating member covers the thin metal wire. When an electrical current is passed through the thin metal wire heat is generated in the thin metal wire. The resistance in the thin metal wire is proportional to the temperature thereof, which temperature is proportional to the current passed through the thin metal wire and the temperature of the liquid or semi-solid in which the sensor with the thin metal wire is disposed. Thus the temperature of the liquid or semi-solid can be determined by measuring the voltage or resistance in the thin metal wire by known measuring devices.
