We need a Arduino circuit, that uses a PT-100 Temperature Sensor to measure Temperatures between -100°C and + 50 °C with an Resolution of 0.2°C. The circuit should not needed to be calibrated. Use of an differential ADC with reference Resistor would be nice.
If using ADC working library for Arduino should be supplied.

The PT-100 is a very common RTD, the PT-100 should be able to be used with two / three and four wire technique. ADS1248 may be considered as an ADC, but any other ADC is fine as well.
