How to use the thermometer pipe?

Pipeline thermometer, as the name suggests, is used to measure the tube temperature. Considering the ways, using our pipeline at the bottom of the thermometer with a magnet. So how to use the pipeline thermometer? Today we have the above figure is a product of our company in the production of pipe thermometer thermometer to tell you how to use pipes. In general, before use, we need to the surface of the pipe to wipe clean, then pipe thermometer pipe surface adsorption, reaction time, wait for 15 minutes at this time as the temperature dial indicator on the surface temperature of the pipe. Pipe also belong to the bimetallic thermometer thermometer one, its working principle is based on the principle of solids expand 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.
