What are Thermocouples?
Thermocouples are made when two conductors (wires) of different metals (alloys) are connected together to form a junction. This connection between the two conductors is typically made by melting the two conductors together using a torch or a flash welding process. The size of the thermocouple is usually specified by the size of the two conductors instead of the junction size formed where the conductors are melted together. The junction size is typically 2.5 times the wire diameter. Since the junction can vary somewhat, it is not the best way to specify the thermocouple size. Wire size is the best determinant.

ECD Thermocouple Solutions
All of our thermocouples have been specifically designed and tested for use in thermal profiling. We offer a wide range of thermocouples, whether you are in electronic product manufacturing, industrial food process applications such as baking or in high temp annealing.
