How high a temp can RTDs go to?


It varies. At the refinery we could buy 500F max RTD from just about any RTD supplier, 700F from just a few and I only found one that would rate theirs to 1000F.



OK thanks I'm thinking oven thermometer and even my missus doesn't burn things that much :) so the 500F versions would do just fine.

Unfortunately I've just laid out the PCB using a MAX6675 so for this one I'll probably stick with that.
