I am also interested in helping design/build some wide range meters. If
we can all pool the info we have it sounds like there might be enough
info there to get something working. The little bit of data i found for
the LSM 11 sensor is only for 260 degrees celsius but if you run with
heater on and near the end of the exhaust pipe the temp should never go
over this?
Any comments.
