However one thing it didn't cover which is what i'm curious on... thermal conductivity is mentioned, but what about electrical conductivity of the electrode depending on the temp of the ceramic insulator?
Look at Water and oil temp sensors.. their merely solid pieces of metal that increase/decrease the voltage going through them depending on temp... it in turn modifies the return signal/voltage back to ecu/guages...
Temperature sensors use a thermocouple. The electrode is a full conductor.
