Introduces a thermocouple characteristics and advantages of each index number

Believe we all know, thermocouple index number can be classified into several kinds of metal, thermocouple, there is also a cheap metal thermocouple. Small make up to you to the next degree, simple component types.

S index number: particularly strong antioxidant, precision yes, comparison was used as a standard thermocouple. Index number:

R and S degree, a lot of performance is basically the same, just electromotive force will be 15% larger than the S or so.

B dividing number: can be used under the condition of oxidation, also can be used under vacuum conditions in a short time, but its electromotive force under the room temperature is very small.

N index number: resistance to low temperature resistance to radiation, thermoelectric emfs is stable, strong antioxidant capacity also.

K index number: strong antioxidant, under the condition of oxidation can continue to use, wide use range. E index number: sensitivity is very high, can continue to use in the oxidizing atmosphere.

J index number: not only can use in oxidizing atmosphere and reducing atmosphere, also compare to corrosion. T index number: belong to inexpensive metal precision thermocouple.
