The hot, or measuring junction is connected to the body whose temperature is going to be measured. The cold junction or reference junction is connected to a body of known temperature. When the measuring junction is placed on something hot a voltage or potential difference between this and the reference junction occurs. This voltage can then be converted into a temperature measurement using thermocouple reference tables which is a process also known as the Seebeck Effect._x000D_ What is a Welded Exposed Junction?_x000D_ An exposed junction is where the thermocouple wires are welded together but not surrounded by the outer sheath. The ends of the wire are directly inserted into the process. This means the thermocouple has a high sensitivity and response time. Welded exposed junctions are more prone to corrosion and are recommended for measuring flowing or static non-corrosive gas temperatures_x000D_ Why RS PRO?_x000D_ RS PRO is our own brand range and brings you a wide range of high-quality, great value products offering you more choice.
