This will theoretically allow a maximum precision of +-0.8K in the range of -200°C...+800°C,
Kai While a PT100 may (and I am not convinced) be operated at 800C, for precision purposes, most authorities wouldn't take them above 600. The drive to the device is not hard to arrange with precision op-amps and good reference resistors, you will find that you need to use a Kelvin connection to the PRT to measure with the requisite precision.
