Enable wide range high-accuracy temp measurements

Many modern industrial, medical, and commercial applications call for temperature measurements in the extended temperature range with accuracies of ±0.3°C or better, performed with reasonable cost and often with low power consumption. This article explains how platinum resistance temperature detectors (PRTDs) can perform measurements over wide temperature ranges of -200°C to +850°C, with absolute accuracy and repeatability better than ±0.3°C, when used with modern processors capable of resolving nonlinear mathematical equation quickly and cost effectively.
