Thermocouples are among the most commonly used industrial elements for temperature measurement. They function by joining two dissimilar metals to form a circuit, generating thermoelectric current from temperature differences between the metals. When there's a temperature difference between the thermocouple tip and reference end, the instrument displays the temperature value corresponding to the thermoelectric EMF generated.
This device supports both on-site measurement and long-distance transmission. It can measure liquid/vapor temperatures and solid surface temperatures, with a significantly wider measuring range than mercury or alcohol thermometers. Suitable for high-temperature applications like blast furnaces and cookery, as well as low-temperature measurements for liquefied hydrogen and nitrogen.
