Hi Guys, this is yet another a great resource for those who are interested in thermocouples.
Introduction
A thermocouple is simple two wires of different material with one side of the ends joined and the other opened.
It works on the phenomena of the thermoelectric current. Means that when both the ends (joined and opened) are subjected to temperature difference, then a small amount of EMF is produced. The question is how "small" is this EMF.
This EMF is just a few micro volts! Too low to be used in any kind of circuits. So what next?!!
Since this EMF is too low to be used and is susceptible to contain noise form the environment, we need to amplify the signal and then filter it. But that's not it!
There is more to it.......for detailed info look at the document below and if you have any question please feel free to contact me.
