Instead of trying to find a sensor that will live at extreme temperatures, (and will most likely fail at the worst possible time), I would suggest that concentrating on the feedstock consistency and knowing the incoming moisture level, this way, you can extrapolate the feed rate from the gas output and spent char amount.
Some things are better done (also wiser and cheaper) doing it "Old School" "X" feedstock at "Y" moisture level, with a "Z" level of intake air, will result in a bed depth of "Q", for a length of time "R", this would mean that "X" amount of feedstock inputted every cycle of "R" will keep the bed depth at "Q". The above equation works for the gasifier I build.
