It seems at the very least that it might be worth checking the resistance
between the sensor body to a/c instrument buss ground (not just the engine) to
be sure that a poor electrical connection isn't causing higher temp
readings.
Hi
Mark,
I agree,
particularly if there's any reason to suspect the readings. It's also
important to make sure you have a good, purposeful ground from your
engine to the airframe, which is probably a lot easier for those of us with
aluminum planes. I really like the grounding plates that Electric Bob
sells (sold ?). It makes a good common ground point for
everything.
We worry
a bit more about grounding in the MRI world than most folks. The scanners
are in RF shielded rooms, and the ground scheme is meticulously followed.
The total signal that we receive from a patient is in the neighborhood of a
millionth of a volt. In other words, if you stand in one spot too long
around my machine, I'll ground your shoes :-)
