Temperature on rad air outlet.

snips

Thanks Ed. Yes on the D5321.
I'll check the software tomorrow when I get it but they probably supply

compiled version so it should run without having to have VB or do
any program modifications. I will also supply all cables and
make up the thermal couples. Figure on mounting the module on a cool
place under the cowl and let me know how long you want the
thermocouple wires.  You will also have to connect it to a source
of 12V.

All we need right at the moment is OAT and one measurement behind
one evap core under worse case cooling conditions. Say climb out.
OAT hot or cold does not matter as all we are looking for is the air

temp

increase through the evap core. Any other measurements you feel like
making are icing on the cake.

I was thinking about measuring the temp on
the outside of the exhaust pipes every four inches to get a feel
for how fast the temp falls off on the pipes downstream from the
engine. Would help when designing mufflers.

I will drill two small holes in my rotor housings next to the spark
plugs and measure cyl head (so to speak) temperature near the
combustion chamber.

BTW I have a third module I bought years ago that measures voltages.

Oh Ed BTW while you are at it. The water temps at the input to
the evap core and the outlet from the evap core would be very
very interesting. Just wrap the TC's to the outsides of the pipes
with a bit of teflon or silicon rubber tape. I'll include
a roll if you don't have any.

Ok Paul,

    Don't have any teflon or silicon rubber tape so if you could send a roll
with the unit I'll send it back with the unit.  I expect we will want to
make several flights to make certain we have enough data to identify any
quirks.  Probably best place for the module would be the coolest side of my
engine (pilot side) as all my exhaust is hidden by intake manifold and block
on that side plus oil sump is on opposite side as well.  I have a blast tube
that routes outside air to my fuel system so probably in that region of the
engine compartment.  But, I'll get back to you with sketch and dimensions
for cable(s)

OK will send both. Teflon and silicone rubber tape. Really neat stuff :-)
