Thermocouples generate thermoelectric potential at the junction of two dissimilar metals for temperature measurement. They support a wide temperature range of -200°C to 1800°C, capable of measuring the temperature of solids, gases, liquids, high-temperature flue gas and molten metals. Featuring long-distance signal transmission, high temperature resistance and vibration resistance, they are the most mainstream contact temperature sensors in industrial applications.
