Order bimetallic temperature time need to pay attention to?

Bimetallic thermometer is a professional measurement of low temperature existing temperature instrument, its working principle is to put 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. Bimetallic thermometer is often used in industrial equipment, petrochemical industry, heating system, pipeline equipment, hvac equipment, construction machinery and general factory, then, order of bimetallic temperature time need to pay attention to what issues? Is widely used because of the bimetallic thermometer, different installation and use of the environment, the parameters of the thermometer base is different, so, in order of bimetallic temperature time, we must first understand installation and use of the environment, so that we can get the exact specifications.
