Suresh,
Below, I have included a link to a tutorial that provides detailed information concerning RTD temperature measurements:
RTD and Thermistor Temperature Measurements
To acquire data from an RTD with your PCI-6031E, most importantly, you will need a current excitation source. By itself, the PCI-6031E will be unable to provide this. However, you can provide your own external source, or you can consider one of National Instruments signal conditioning options for RTD measurements with your PCI-6031E. For example, an SCC-RTD01 module in an SC-2345 carrier provides a 1 mA excitation source, as well as all of the other signal conditioning require
d for RTD measurements. Below, I have included links to information detailing SCC Signal Conditioning Systems and product pages for the SCC-RTD01 module and the SC-2345 carrier:

Good luck with your application.
