You're in a generous mood today
(01-21-2009, 02:55 PM)winmutt So these are K type Thermocouplers I am almost certain of it. Even though I was getting a change in resistance it appears the K type thermocouplers generate micro voltages. I can't interface with the Arduino directly but I *can* get one of these (http://reprap.org/bin/view/Main/Thermocouple_Sensor_1_0) and free up an analog port.
Forget those analog sensors (that board still sent an analog signal to your micro)... check out this one. Thermocouple straight to digital SPI/I2C serial bus.

You can get the PCB made for dirt cheap (no need for a 100+ board run for personal stuff) http://www.batchpcb.com/
Also check out the parent company of Batch PCB... www.sparkfun.com It's a really awesome site.
(01-21-2009, 02:55 PM)winmutt I don't understand why I can't use it as a thermistor as it is providing a change in resistance
If it was providing a change in resistance you would apply a voltage and measure the voltage drop using a voltage divider. All you do with a thermocouple is measure the voltage. You don't actually apply any at all. The thermocouple actually generates its own voltage due to the contact with two different metals.

'05 E320 CDI - 118k - Faaaaaast!!
'87 300TD - 317k - Cracked head... but an OM606 is on the way!
'79 300SD - 295k - Bad engine = project car!
