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.
