As far as I'm aware, only "metallic" temperature sensors are linear (for example PT100 sensors, and yes, the PT stands for platinum). PT100 sensors aren't linear at all! Have a look at figure 7 of http://www.maxim-ic.com/appnotes.cfm/an_pk/3450 The KTY-series is widely used for automative applications. They aren't linear either, but are cheap and stable. Here are examples: http://www.8052.com/forum/read/74677 http://www.8052.com/forum/read/56295 Datasheet of sensor: http://www.datasheetcatalog.net/de/datash...10-6.shtml Kai |
