The Basics of Thermocouples - Circuit Cellar

· In a physical circuit, parasitic thermocouples are formed at every solder joint, connector, and even every internal IC bond wire. If it weren’t for something called the Law of Intermediate Metals, these parasitic junctions would cause us endless trouble. The Law of Intermediate Metals states that a third metal may be inserted into a thermocouple system without affecting the system if, and ...
