temperature sensing device is a special alloy sheet metal has a memory function, this metal due to thermal expansion and contraction, driven thermostatic valve action. Before such products need to be rigorous experimental factory and its temperature detecting means, while the metal in the presence of frequent stretching and bending fatigue fracture characteristic change problems and malleable metal, the temperature be such life and affect the accuracy of the device. if you are interested in, then you can consult our company.
