Hi,
I have question regarding RTD measurement.
If I have an RTD. Assuming that i can provide an excitation current, can I use the NI 9202 (Analog Voltage Input Module) to measure the Voltages across a 3-wire RTD to and using an algorithm measure the temperature?
I just want to know if its possible to do this.

I suppose you could have an external exitation voltage and the external bridge crircuit for the three wire system - but the voltage you are trying to measure will be fairly small within the +/-10V range of the module (but depend on excittation voltage and bridge). Why not just use the NI-9217 which this is specifically for.
