DN32 bimetallic thermometer inserted in the pipeline depth choose how much good?

Bimetallic thermometer is a professional to measure - 50 to 500 c temperature field instruments. It USES the field widely, the scene display temperature, intuitive and convenient, safe and reliable, long life, fast reading. Working principle of the bimetallic thermometer 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. In all kinds of pipeline can often use the bimetallic thermometer. Today let's DN32 pipe, for example, for a short line of DN32 insertion depth of the bimetallic thermometer choose how much good? First of all, we know that DN32 refers to the inner diameter of 32 mm 38 mm, 3 mm wall thickness, diameter of the pipe. Second double metal thermometer temperature measuring method is to heat pipe can be inserted into the pipe to be tested, and used on pipeline bimetallic thermometer is a mounting base, usually the center of the pipe temperature is the most close to the real temperature. 'Accordingly, pipes in the bimetallic thermometer inserted depth of: the height of the base + 1/2 pipe diameter. We assume that the mounting base height is 25 mm, then DN32 bimetallic thermometer inserted in the pipeline depth should be: 19 = 25 + 44 mm.
