K, E type thermocouples
Thread Content
I have several thermometers; how can I quickly and effectively determine whether they are K-type or E-type thermocouples?
Place it in boiling water, measure the thermoelectromotive force, and consult the calibration table to find out the value
At the same temperature, the mV values output by these two thermocouples with different ratings will definitely be different.
A cold-end value is also needed, right? Should it be added or subtracted?
A cold-end value is also needed, right? Should it be added or subtracted?
The temperature obtained by subtracting the cold-end temperature from the hot-end temperature is then used, along with the thermoelectric potential, to consult a table to determine which value matches
The simplest way is to measure the thermoelectric potential in boiling water...
Measure the thermoelectromotive force in hot water, consult the calibration table – the correct answer is above
