Subject: [FlyRotary] EGT/CHT wiring
I've been wrestling the wild EMU and need some help! (actually, it has
been pretty easy, and fun, in a wierd sort of way).
I purchased the EGT probes with the weld-on bungs from ACS. The problem
is
the leads are only about a foot long and they have ring terminals on the
ends. Do I cut these and solder (or weld) extensions so they will reach
the EMU box? Would a standard terminal block work? Any other solutions?
For the CHT probes, I have drilled a 1/8" hole in the web next to each
leading spark plug. The bottom of the hole stops at the steel liner of
the
center housing. I have ordered "J" type thermocouple wire and will tig
weld the connections. My question is... do I need to insulate the
junction
to prevent it from making contact with the metal housing, or does that
matter?
Depends on sensing circuit, probably doesn't matter.
I would suggest not potting them. You could put a small amount of silicone
fluid for heat transfer in the hole, but probably not necessary.
Should I pot these into the holes, or just stick them down into
the holes and leave it go at that?
