hello is it possible to create a circuit by an lm324 and a 2n3904 transistor to make 4-20ma?
i have this circuit and its working great only differense is the digipot that one is a X9C103 10kohm but i can only get around 5 to 17 ma. tryed to change values of resistors but i have a lack of know how
so if anyone can help me i will be happy
thank you
