Comparative Investigation on the Quality of Sensitivity of Six Different Types of Thermocouples

Sensitivity quality of thermocouples is an important parameter in temperature measuring, it affects on the accuracy measuring results. Metals type which used play a prominent role determining level and sensitivity. Nine minerals were investigated compared with each other, as these metals contribute to composition six types E, J, K, T, R S. Three factors such metal type, magnetic field, chemical studied find out their effects sensitivity due increasing decreasing thermocouples. Research methodology has data collection analyzing related 6 The results showed that E- higher sensitivity, then but S have lower most ranges, also, copper, nickel, chromium can give more than platinum rhodium. Also, this research assist manufacturers further connection between accuracy, addition, for selecting appropriate medium being measured.
