Hi Jimmy
http://www.datasheetarchive.com/temp...datasheet.html should help point you in the right direction. Most sensors used are Thermistors NTC and usually 10k but can come in like 2k 5k 20k 100k etc. If you measure your sensor at around 25degC you should get an idea of how many k it is.
Most as suppliers of controls suppliers will charge from $25 to $250 for a sensor which you can buy from jaycar electronics for less than $5.
