RTD measurement circuits The two most common methods to measure an RTD are constant current excitation (Figure 1 ) and constant voltage excitation (Figure 2 ).

For example, a Pt100 RTD has a resistance of 100 Ω at 0 °C. An accuracy of +/- 0.15 °C at 0 °C is typical, but accuracies down to +/- 0.03 °C are available.

/* This example shows how to use an AD7793 converter to perform successively two measurements: 1) a single voltage reading in the range from 0 to 0.58 V on AD7793 channel 2 (0.58 = 1.17V AD7793 ...

An RTD is a temperature sensor that operates on the measurement principle that a material’s electrical resistance changes with temperature.

A mixed analog-digital signal analysis of temperature measurement circuits are proposed in this paper. With the combination of both self-balanced Wheatstone bridge (WSB) and direct digital converter ...
