K Type Thermocouple(Nickel-Chromium / Nickel-Alumel)Manufacturers & Suppliers

The Type K Thermocouple has the broadest temperature range. It is made up of a non-magnetic positive leg and a magnetic negative leg. Traditional base metal is utilized in K Type Thermocouples, which allows them to perform at high temperatures and give the broadest working temperature range. Nickel, a magnetic metal, is one of the component metals of K Type Thermocouples.

When magnetic material approaches its Curie Point, which is roughly 185 degrees Celsius, K Type Thermocouples exhibit a variation in output. The K Type thermocouple performs effectively in an oxidizing environment at temperatures up to 1260°C (2300°F), with a tolerance class of 1.5 K between -40 and 375°C.

K Type Thermocouple Composition

The positive leg of a K Type Thermocouple is made up of 90% nickel and 10% chromium, whereas the negative leg is made up of 95% nickel, 2% aluminum, 2% manganese, and 1% silicon. With a sensitivity of around 41 V/°C, this is the most popular general-purpose thermocouple.
