Thermocouple sensor output voltage is how much?

Thermocouple ( 热电偶) Is commonly used in temperature measuring instrument of temperature measuring element, is a kind of instrument at a time. It directly measuring the temperature and the temperature signals into a thermoelectric emfs, through electrical instrument ( Secondary instrument) Convert the temperature of the measured medium. The appearance of all kinds of thermocouple is often due to the need to vary, but their basic structure is roughly same, usually by the hot electrode, insulation sleeve to protect the main parts such as pipe and connection box, and usually display meter, recording meter and electronic regulator.

thermocouple sensor output voltage is millivolt values, the output size based on the index number of different and different, as an example, at 400 degrees S index number is 3. 26 millivolts, B index number is 0. 786 mv, K index number is 16. 395 mv, T index number is 20. 869 mv, E index number is 28. 943, millivolt, J index number is 21. 846 mv. Thermocouple could be selected according to the temperature and the environment situation. And with the same degree, compensation of line and display usage.
