Hi,

Did you look at this scheme?

1. **broken link removed**
This guy is using LM358 opamp along with a LM385 reference IC, to read from PT100 sensor. You also could use this scheme.


2. Another scheme that uses ADS1247:

Hello,

thank you for your respond. One more question, could I use 2 wire pt100 instead of 3 wire?
