Thermocouple

RTDs are completely passive sensing elements, requiring the application of an externally-sourced  electric current in order to function as temperature sensors. Thermocouples, however, generate their own electric potential. In some ways, this makes thermocouple systems simpler because the device receiving the thermocouple’s signal does not have to supply electric power to the thermocouple. The self-powering nature of thermocouples… Read More »
