WSS series bimetallic thermometer how to order

Bimetallic thermometer is used widely, also can call it WSS series bimetallic thermometer, the name is generated by the rules of the serial number of it. WSS series bimetallic thermometer in the field of widely used, often used in industry, petroleum, chemical, heating system, pipeline construction, machinery manufacturing and general factory. Order WSS series bimetallic thermometers must know the following parameters: 1, clearly indicate product model, namely the table plate diameter, measuring range, installation direction, thread specification and material, protecting tube length and material, diameter and material of the shell, precision level. 2, need outdoor and anticorrosive varieties to be marked. 3, users have special requirements, must be specific. WSS series bimetallic thermometer works 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.
