Hi everybody, I'm trying to collect the data from a HART pressure transmiter (Rosemount 3051S) with LabVIEW, I tried to put a 250 ohm resistor in the loop to convert the 4-20 mA output to 1-5 VDC output, so I can capture it with our current I/O DAQ, but the signal is fluctuating pretty bad, and the error is way too high to be used. Since the transmiter is kinda different, the power input pins are also used for signal output, I wonder if it is possible to just get a current input DAQ from NI and capture the signal directly?
