Can anyone suggest the best method (or design) to convert a 0 to 38 mV
pressure transducer signal to a 4 to 20 mA signal that I can send down
1000' of cable? I'm aware of the Burr Brown current transmitter devices,
but am seeking a simple op-amp solution. The BB chips need a much larger
voltage span as input.

Thanks,
