Digital OAT

Does anybody in the group have a digital OAT indicator?

We've just put a new single piece windshield in our plane and moved the
standard OAT gauge to the pilot's side window. Now we've decided to put all
new 1/4" side windows in and rather than drilling a hole through a brand new
window, I'd like to consider one of the digital OAT's such as Davtron or EI.
I'm wondering exactly how they are installed and where the temp probe is
located.

Thanks,
Jim

I put a Davtron M303 in my cherokee 140. The temp probe was installed
on the pilot side of the fuselage just aft of the cowling. In my case I removed
a non-functioning hobbs meter and put in the round OAT display. I chose
to install a digital OAT probe because I just replaced the windshields on
my cherokee and didn't feel like putting back the thing that caused stress
factures in the "glass"

Thanks Bob,
Can you describe the probe please? How big is it, how far outside the skin
does it extend? We've got un-used radio cooling "scoops" that extend
outwards along the sides of our nose and I was hopeing to install the probe
on the back of this panel placing the probe inside the scoop to protect it
from "the cleaning lady".

um, it's about 1" long and a little less than 1/4" in diameter.

Let me go over to the airplane Saturday and I'll take a measurement
of the length.

Thanks. No need to go to any extra trouble, I think we could also put it
directly in front of the windshield by reaching up through the side panels
on the nose, that way it will get good ram air blowing on it and won't have
any restrictions that could build up ice around it.
Thanks!

A JPI? Never.

It is NEVER extra trouble to go over to my airplane
(besides, it's only 7 miles from my house).

The probe is slightly less than 1.25" long, but longer than 1 3/16 inches.

Hey Jim...we installed a Davtron in the Arrow. OAT probe is in the
middle of an inspection panel on the bottom of the left wing. IIRC,
it's the forward most panel and the first one from the bottom of the
fuselage. The Davtron works great. Way easier than trying to read the
old OAT in the windshield.

Slap! Hey, you asked for it. Repeat after me Jim, "Digital
OAT...Digital OAT...all I want is a Digital OAT".

I put a Davtron in my Maule. I drilled a hole in the side of the cabin just
behind the cowl for the temperature probe. I placed in in a stripe so it would
be unobtrusive. Drilling through the cabin side allowed me to avoid running a
wire through the firewall.

I came off the main electrical buss with a 1/2 amp breaker and 22 gauge wire to
the gauge. My Maule had plenty of spare holes in the panel, so I just popped the
gauge in one. Did the work under supervision. The local FSDO required a field
inspection (no big deal). The breaker needs a label.
