Figure 1: R-Tª curve of a Pt100 in the range of -200ºC to 850ºC (A)


Figure 2: Inverse functions with different constant G


Figure 3: Curve of a Ni100 nickel RTD (in pink), and coincidence with the inverse function (in red). The error in the temperature reading per 100 is shown in cyan. The points considered for calculating the coincidence are -80°C, 20°C, and 260°C (red points on the fuchsia curve)
