Introduction to Thermocouples
A thermocouple is a temperature – measuring device that consists of two different metals joined together at one end. When there is a temperature difference between the junction (the joined end) and the other ends of the two metals, a voltage is generated. This voltage is proportional to the temperature difference, allowing for the measurement of temperature. Thermocouples are widely used in various industries such as manufacturing, power generation, chemical processing, and food production due to their simplicity, reliability, and wide temperature measurement range.
