The basic principle of thermocouple temperature measurement is that two different material conductors form a closed loop. When there is a temperature gradient at both ends, a current will flow through the loop. At this time, there is an electromotive force between the two ends-thermal electromotive force, which This is the so-called Seebeck effect. According to different materials, thermocouples are divided into T, J, E, K and other index numbers. The advantage of thermocouples is that they can be reused in harsh environments. Even broken thermocouples can still be used as long as they are connected together and can ensure accuracy.
Operating Temperature Description:
K-type indexing number: long-term 0~1000℃, short-term 0~1300℃
E type indexing number: long-term -200~900℃
N type indexing number: long-term -200~1300℃
S-type indexing number: long-term 0~1300℃, short-term 0~1600℃
Type B indexing number: long-term 0~1600℃, short-term 0~1800℃
R type indexing number: long-term 0~1200℃, short-term 0~1500℃
