Magnetometer??

Hi Dan,
this one is fairly small, it feeds a computer for a EFIS system. Grand
Rapids uses them on their system. From what I heard once it's setup your
finished with it. That sure beats the heck out of adjusting for drift every
15 minutes on a heading indicator.

Aha,I was wondering what this thread was about. I guess it is a
matter if definition. The basic definition of a magnetometer as I
understand it is to detect and measure magnetic fields. None of the
magnetometers I have used were small enough, light enough or logically
located in a cockpit. Then again none were connected to a computer.

I installed flux valves is extraodinarilly difficult places on some
aircraft and amazingly easy on others (if you aren't afraid of heights).
I have come to the conclusion there's a conspiracy among the makers of
flux valves to have them fail in extremely hot weather, extremely cold
weather or when I was the only one left in the shop who has swung one.
In the latter case you would have seen some rather large swing crews
MC-1 compass swing set ring a bell, anyone?

I wonder if the magnetomer you are using is anywhere near as
sensitive to induction as a flux valve. If it isn't I'd say you could
get away with mounting it resonably distant from electrical systems. If
you have ever seen a mag compass drift when lighting, pitot heat or the
like is turned on/off you'll have an idea of what too close is.

Other than that I'm not sure what I can do offer. Have you contacted
the maker?
