Bimetallic thermometer order information

The working principle of bimetallic thermometer 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 industry, petroleum, chemical, heating system, pipeline construction, machinery manufacturing and general factory. Even if the bimetallic thermometer is used widely, but as long as it is under the same installation environment, the parameters of the thermometer is consistent basically. We sort out the order need to know the parameters of the bimetallic thermometer, specific as follows: 1, clearly indicate product model, namely the surface diameter, measuring range, installation direction, thread specification and material, protecting tube length and material, the shell material, precision level. 2, need outdoor and anticorrosive varieties to be marked. 3, users have special requirements, must be specific.
