WebType J thermocouples have a more restricted potential range than type K at –200°C to +1,200°C, but a higher sensitivity of about 50 μV/°C. These thermocouples are very linear in the range of 149°C to 427°C. Type E thermocouples have a potential range of –270°C to 1,000°C, and have the highest output versus temperature change of any ... WebA thermocouple works, perhaps unsurprisingly, on the basis of thermoelectrics: as noted above, when temperature changes at the hot junction relative to the cold junction, it creates a change in voltage across a closed circuit consisting of dissimilar metal wires.
