Hi all
I want to design a 2nd order low pass active filter circuit for thermocouples , can anyone has a design of this which you have already tried and works well with thermocouples? What resistor and capacitor values you used?
I have studied the NI tutorials for signal conditioning of thermocouples.It is written that the frequency of thermocouple signal is near about 4 Hz. What is the cutoff frequency that you set ?
Please send me the circuit or a link of this. Any help will be greatly appreciated.
