Type K Thermocouple Thermometry Basic Theories:Type K Thermocouple is to use this effect to work: two different conductor or semiconductor materials A and B welded together to form a closed loop, When there is a temperature difference between 1 and 2 which are the attachment points between two conductors A and B, then electromotive force arises between these two, thus forming a size in the loop current, a phenomenon known as the thermometric effect.
In order to guarantee the Type K Thermocouple is reliable, steady work:
1. Hot electrode of the two thermocouple welding must be strong.
2. Two hot electrodes to each other should be well insulated to prevent short circuits.
3. The connection between compensation wire and thermocouple free end must be convenient and reliable.
4. It should be able to guarantee protection casing has full isolation between hot electrode and harmful media.
