Many thermocouple solutions are provided fully assembled and connected to a subminiature plug (SMP) with polarized blades, allowing the thermocouple to quickly be attached to a data logger. While these thermocouple solutions often save time and effort, it can be helpful to understand the basic principles of how a thermocouple is connected to an SMP. This can be especially useful when troubleshooting unusual temperature readings that may not be realistic for the application at hand.
