For a platinum RTD, the Callendar-Van Dusen equation describes the relationship between resistance and temperature as: R(t) is the RTD resistance t is the temperature R 0 is the resistance of the RTD ...

In Figure 1’s circuit, R4 is an RTD. As per the platinum RTD’s temperature versus resistance table (DIN EN 60751), R4 is 100 Ω at 0 °C and 212.2 Ω at 300 °C. This circuit is designed for the range of ...

Temperature sensitive materials used in the construction of RTDs include platinum, nickel, and copper; platinum being the most commonly used. Important characteristics of an RTD include the ...
