Can anyone tell me if it's possible to monitor the ma output of a pressure transducer or any other sensor for that matter. I'm working on replacing my older style electromechanical well controls and controlling them via a pic and heavy duty 220amp relays. I have 2 wells and they don't always stay in sync.

I have access to a cheap pressure transducer 0-150psi and the output is 4 to 20ma. I can get one for a couple of dollars but I didn't see a post anywhere that anyone has written any code or has any example of reading milliamps.

If anyone has an example I would appreciate it.
thanks
David
