WebFigure 5: Charting temperature vs. voltage. Although a thermocouple does not directly tell us the temperature of the measurement junction, it does give us a voltage. This voltage is a readable electrical signal that is dependent on the difference in temperature between the measurement and reference junctions. WebSeries resistance along the lines of the thermocouple—Because thermocouples are conductors, the parasitic resistance in the conductors or attached circuitry may impact …
