RTDs have higher accuracy and repeatability and can replace thermocouples in some industrial applications below 600 °C.
In 1821, the German physicist Thomas Johann Seebeck discovered that a magnetic needle held near a circuit made up of two dissimilar metals got deflected when one of the dissimilar metal junctions was heated. At the time, Seebeck referred to this consequence as thermo-magnetism. The magnetic field he observed was later shown to be due to thermo-electric current. In pract… WebbThermocouples produce a voltage output that can be correlated to the temperature that the thermocouple is measuring. The documents in the table below provide the …
WebbThe thermocouple is actually just a soldered wire inside the nut, which adds a thermal mass and attachment point. Loosening the nut will affect the thermal junction, yoh should use thermal grease (if possible) and tighten well.
