Wiring an RTD temp sensor and calibration

Hello I was wondering if anyone had an experience in wiring a 3-wire PT100 RTD sensor into an Arduino. What wires go where? converting the resistive signal to voltage so the arduino can read it? Converting the voltage read in to a temperature? Simple read in program to test it?

Here is the sensor, I am a little unsure which wires go where. 2 red and one white wire. http://www.auberins.com/index.php?main_page=product_info&cPath=20_15&products_id=96

Any advice would be greatly appreciated. Thanks

P.S.: Get rid of all analog problems and use a DS18B20.

This is a better solution if you don't need the temperature range of a Pt RTD.

On the other hand, if you end up using the RTD, the white wire would go to ground and one of the red wires would go to the series resistor that forms part of your voltage divider. The other red wire goes to the input of your instrumentation amplifier or high precision ADC.

Already have the RTD will be using it for sure. Any more in depth detail would be appreciated. Thanks

It sounds like your level of expertise is low. Tell us what temperature range you'll be using it over and the length of the wires between it and your instrumentation.

What is wrong with the detail in the link of openenergymonitor.org

Here is another good explanation, http://learn.adafruit.com/thermistor

This is too much detail, http://en.wikipedia.org/wiki/Resistance_thermometer

Something to bear in mind when selecting a series resistor is that a PT100 RTD's resistance changes about 0.4 Ohms per degree centigrade.
