Shanghai tankii, specializing in producing thermocouple wire,
thermocouple cable, thermocouple MI cable.
A typical thermocouple construction consists of a pair of
dissimilar metals that are electrically joined together at the
sensing point and connected to a voltage measuring instrument at
the other end. When one junction is hotter than the other, a
thermal “electromotive” force (in millivolts) is produced that is
roughly proportional to the difference in temperature between the
hot and cold junctions.
Tankii Type K thermocouple is composed of a Nickel-10% chromium (+) wire versus a nickel-5% aluminum and silicon (-) wire. This type of thermocouple should only be used in oxidizing or inert atmospheres with a service temperature range between -200°C and 1260°C (-330°F to 2300°F). They are most widely used at temperatures above 540'C (1000"F) due to superior oxidation resistance in comparison to Types E, T, or J. There are some conditions which should be avoided when using Type K thermocouples. Vacuum applications should not use Type K due to vaporization of chromium in the positive element. Tankii Type K thermocouples should not be used in Sulfurous environments since both elements will rapidly corrode and the negative element will eventually fail mechanically due to becoming brittle. Reducing atmospheres should also be avoided. Low oxygen levels can cause the Green-Rot phenomenon in which the chromium in the elements starts to oxidize causing large negative drifts in calibration.

Characteristics:
The thermocouple wires have excellent performance and are
extensively used in the temperature measurement and control in
different fields, such as metallurgy, chemical industry, petroleum
industry, machinery-electric industry, energy industry, agriculture
and military industry.
Tankii products conform to the standards of IEC584 -1and IEC-2.
