Hi All,
I have to design a thermocouple circuit using a K-Type thermocouple. The output should be 4-20 mA(4 mA at 25degrees Celcius and 20 mA at 40 degrees Celcius). I can just use my multimeter to measure the output current. Apparently there is a simple current follower circuit that I can build to achieve the desired 4-20 mA output, using only one thermocouple. I have been reading for a full day and decided to join this blog after realizing that the task at hand might be more complicated than I thaught,
Any advice or circuit diagrams?
Help would be much appreciated!
