i am facing same problem with PT 100 which is directly connected to RTD module of Rockwell micrologix PLC. So suggest me the solution.
Welcome to AVRFreaks.
HOWEVER... what does your demand have to do with Atmel products?

If your RTD is already driven by another device, there is very little you can do. You can measure the voltage across it, but without knowing the current, you have nothing. This is true for any measuring device (that reads an already-driven RTD) - there is no magic that a microcontroller can pull out of the hat for you.
