A thermometer is how to work the surface of the magnet?

Single magnet surface thermometer belongs to the bimetallic thermometer. Its working principle is based on the principle of solid heat expansion, the two pieces of expansion coefficient difference is very big pieces of metal welded together. When the temperature changes, the difference is very big, caused the different expansion coefficient of expansion and contraction, the deformation of sheet metal bending. According to different deformation and produce different momentum, momentum to drive the connection shaft and the other end of the indicating needle, indicate the temperature. It has a magnet on the back of, firmly adsorbed on the measured medium, thus have to list the magnet surface thermometer, temperature, as long as the single magnet surface adsorption thermometer in clean metal surface under test, wait for about 15 minutes, reaction time, this time as the temperature dial indicator on the surface of the measured medium temperature. This simple and effort of temperature measuring method is one of the highlight of single magnet surface thermometer. Single magnet surface thermometer generally used in the pipe, or the mould manufacturing environment.
