K type Thermocouple RTD temperature sensor RTDs Thermistors K type thermocouple

K type thermocouple) also known as iron - Kang Tong is also a thermocouple, cheap cheap metal thermocouple. Its cathode (JP) on behalf of the chemical composition of pure iron anode (JN) for copper nickel alloy, often vaguely called Kang Tong, the name of its chemical composition: 55% copper and 45% the nickel and a small but important manganese, cobalt, iron and other elements, although it is called Kang Tong, but unlike Kang Tong and Kang Tong copper - nickel - chromium - Kang Tong, EN and TN can not be used to replace.

The areas covered iron Kang Tong thermocouple measuring temperature of -200~1200 DEG C temperature range, but usually used for the 0 ~750 C.

Thermocouple good degree of linearity, thermoelectric large, high sensitivity, stability and uniformity is good, the advantages of cheap, widely used by users. The type J thermocouple can be used in vacuum, oxidation, reduction and inert atmosphere, but positive iron oxidation at high temperatures is fast, so use temperature is limited, can not no direct protection at high temperatures for curing atmosphere.
