Product Description: Thermocouple is a simple, robust and cost-effective temperature sensor used in a wide range of temperature measurement processes.It consists of two different types of metals, joined together at one end. When the junction of the two metals is heated or cooled, a voltage is created that can be correlated back to the temperature. Thermocouples are commonly used in a wide range of applications. Due to their wide range of models and technical specifications,it is extremely important to understand its basic structure, functionality, ranges as to better determine the right thermocouple type and material of thermocouple for an application.
