I.Applications: it is usually combined with display instruments, recording instruments, electronic computers, etc. to directly measure the temperatures of liquid, vapor and gaseous media and solid surfaces in the range of 0 °C to 1300 °C in various production processes.
II. Features: less thermal response time and less dynamic error; Flexible installation for use; Large measurement range; High mechanical strength, good pressure resistance;
III. Working principle: the electrode of armored thermocouple is composed of two different conductor materials. When there is a temperature difference between the side measurement end and the reference end, thermoelectric potential will be generated, and the working instrument will show the temperature corresponding to the thermoelectric potential.
