Hello!
I am using the circuit shown here **broken link removed** for temperature measurement.
I am getting Vo = 0.72V @ 0 degree C and Vo = 2.83 @ 850 degree C. The function is not linear. I want to know how to calculate the RTD resistance and temperature for Vo. Resistance of RTD increases 0.389 Ohms / degree C. And RTD resistance @ 0 degree C = 100 Ohms. i.e., @ 100 degree C, the RTD resistance will be 138.9 Ohms.
