Do you know where the magnets with thermometer?

Our instrument magnet temperature scoring two kinds, one kind is single magnet thermometer, the other is a double magnet thermometer. Is named by its structure ( There are several of the magnet) 。 Magnet is one of the bimetallic thermometer 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. Magnet thermometer it is mainly used to measure the surface temperature of the measured medium, when used as long as the magnet thermometer adsorption on the surface of the measured medium that clean, waiting for 15 minutes, reaction time, the temperature of the indicator on the dial is the surface temperature of the measured medium.
