System block diagram. The constant current source drives the temperature sensor Pt100 to convert the resistance signal (80.31 to 280.98) into a weak voltage signal (0.08 to 0.28V). In the signal conditioning circuit is converted to 0 ~ 2. The voltage signal between 2V, the C8051F410 on-chip system A/D samples the voltage signal.

To avoid employing a microprocessor, we can use the analog approach to perform accurate linearity compensation. Here is the circuit : This circuit linearizes the raw PT100 output. Without any linearization, the output of the sensor deviate from its linear model about -1.5 to 0.5 Celsius degree within -50 to 125 Celsius degree operating range.
