texas instruments Incorporated General Interest Analog linearization of resistance temperature detectors By Bruce Trump Staff Technologist resistance temperature detectors (RTDs). Figure 1. resistance of Pt100 RTD versus temperature are commonly used in industrial and scien- tific temperature measurements. The most common types are pure platinum (Pt) 400. formed into wire or evaporated in a thin film on a substrate. They rely on the funda- 350. mental temperature -dependent resistance 300. properties of this noble metal. They are very stable and useful at temperatures resistance ( ). 250. ranging from cryogenic to over 800 C. A. wide range of physical configurations, 200. resist ance ranges and accuracies is avail- Curvature due to 100 at 0 C second-order The commonly used notation Pt100 150. nonlinearity indicates a 100-W resistance at 0 C.
