Hi,
I have a dpm342 4-20mA loop powered LCD readout, and I want it to read a 36k variable resistor with a 5v supply over its entire range. I know I have to use a op amp, but not sure which one, or the circuit I need. Can anyone help me?
In summary, I need a circuit to convert a signal of (541.61uV - 3.97V) to a current of (4mA to 20mA).
Cheers
