A Basic Guide to RTD Measurements
copper. The PT100 is a common RTD constructed from platinum with a resistance of 100 Ωat 0°C. RTD elements are also available with 0°C resistances of 200, 500, 1000, and 2000 Ω. 1.1 Callendar-Van Dusen Equation The relationship between platinum RTD resistance and temperature is described by the Callendar-Van Dusen (CVD) equation.
