I have been tasked with creating a thermomether using a RTD, more specifically a pt1000, also using a wheatstone bridge. Conceptually I think I have figured how to do it. I build the wheatstone bridge, that works as a voltage divider, with the pt1000 integrated in it. Then we use 2 amp ops, one first to amplify the signal, and one after to substract the offset voltage of the pt1000 (i think), or as my professor calls it, to create a differential step. The problem is that I lack actual electronic knowledge, so creating a schematic circuit is proving to be a problem. I have come across some in the internet, like this: https://i.gyazo.com/573ecbc4d7d5ec284f3a7b72b2bad398.png (though this one uses a pt100), but I think that the amp ops are in a different order, and I cannot even spot the wheatstone bridge. Could someone give me some insight?
