T type thermocouple is also called copper-constantan thermocouple. Graduation number T. Measuring range -200~+350℃. T type thermocouple is also the best thermocouple for measuring low temperature and cheap metals. Its positive terminal (TP) is pure copper. The negative electrode (TN) is a copper-nickel alloy called constantan. The measurement temperature range of T type thermocouple is -200~350℃.

T type thermocouple working principle
The ends of two conductors of different compositions are welded to form a loop. The direct temperature measurement end is called the measurement end. The terminal end is called the reference end.
When there is a temperature difference between the measuring end and the reference end, a thermal current will be generated in the loop. Connect the display instrument. The instrument indicates the corresponding temperature value of the thermoelectromotive force generated by the thermocouple.
The thermoelectromotive force of the thermocouple will increase as the temperature of the measuring end increases. The size of the thermoelectromotive force is only related to the material of the thermocouple conductor and the temperature difference between the two ends. It has nothing to do with the length and diameter of the hot electrode.
More Featured Temperature Sensors
T type thermocouple has the advantages of good linearity, large thermoelectromotive force, high sensitivity, approximately linear temperature and good replicability, fast heat transfer, good stability and uniformity, and low price. Especially at -200~0℃ temperature When used in the area, the stability is better, and the annual stability can be less than ±3μV. After low-temperature verification, it can be used as a second-class standard to transfer low-temperature values.
In addition to T type thermocouple, we at Sino-Inst also supply various types of temperature sensors and temperature transmitters. Including K type, S type, armored, probe type, etc. If you need to purchase T type thermocouple, or have related technical questions, please feel free to contact us.
