 Actually, I am working on a temperature compensated oxygen sensor for =
fuel/air measurement in the rich region.  Getting the oxygen sensor with =
a built in thermocouple has been the most difficult part.  I am curious =
why you didn't suggest a thermocouple for temperature measurement?  It =
seems the best method to me, but I've been wrong many times before:-).
