Low Current Measurement (without ammeter)

Hello Everyone,

I have an application that uses 3 displacement sensors with analog
current output from 0 to 20mA. I have a real time DAQ system that only
measures voltage from 0 to 10V. I have read the previous response to
Pradheep's question and it seems like the current values are too high
to get the kind of precision that I need. I was wondering if I could
use the resistor in series method and if there was some trick that
could help me develop this setup? Any help at all would be appreciated,
because I've never had to measure currents like this before so I'm a
little beside myself trying to figure this one out...Also if the
resistor "shunt" is placed in series what kind of accuracy can be
achieved?
