If the hole in the panel is too big for a POT, glue or rivet a reducing washer
to the other side of the panel. Mount a 10K pot and put the knob from the EPL1012
on the pot shaft. Connect the pot center wiper to SkyView pin 25. Connect
12 volts across the other two pot terminals.

Polysulfone enclosure material for this device is
very compatible with motor fuels.
I proposed using this sensor as a component of
an upgrade to a series of low liquid level sensors
I worked on for Electro-Mech WAaaayyy back when . . .
We crafted a series of optical liquid level sensors
that were widely used on Beech products. It looks
like they still make some version of them . . .
http://tinyurl.com/hgs24nt
When the Premier was still under development, I
became aware of dismal failure rate in these
devices. Given the simplicity of the product,
it was rather astounding. Dean Matson and I
were co-developers of the original concept and
we were working together at Beech's Targets
division when the news came to us.
To make a long story short, this program proved
to be a fine example of what can happen when a
small, tightly coupled design, development and
manufacturing operation gets bought out and
'upgraded' with all the albatrosses and millstones
of the parent corporation after a buyout.
I suggested that the fast-turn solution for the
failures was to modify a GEM sensor to fit into
the stock Electro-Mech enclosure. Had this
problem surfaced in the same regulatory and
business environment I enjoyed in 1985, we could
have put the fix into production in a couple
months at most. But in 2004 . . . well . . .
I was pretty busy fighting other fires then and
I don't know what they wound up doing to fix
the EM product . . . but the short answer to your
question is that the GEM sensor is well suited to
the application you are proposing.
For those interested in the history of this technology
in aircraft, I've posted a few snapshots of my own
experience with it at http://tinyurl.com/h586hp9

Hi Paul,
You can use a 2-10 (on-on-on) switch like what Bob shows on his Z-16 drawing as
a master switch. You could wire it like Bob shows in Figure 11-17 on page 11-19
of the AeroElectric Connection. That's what I did for my landing light to have
the down position "off", center "landing", & up "wig-wag". You could configure
whatever order you like.

Don,
THANKS for the link however sadly that schematic is for the OFF-ON
switch.
Bob says> Do you have one of these switches in hand?
I do not have the switches in hand however this is what the vendor has
provided thus far (he is expanding his offerings of switches and he is
working on getting me a schematic of what terminal spades are
electrically
connected when the switch is in each position.
..
Cheers!!!

Subject: | Re: Off-On-On Switch |
Thanks everyone for the feedback. It seems like all the switches mentioned
are progressive. Am I interpreting things correctly in that power feed to
the wigwag module will of course cause the lights to wigwag. When power is
applied directly to the lights without removing the power from the wigwag
module then the lights go on steady with no harm done to the wigwag module?
I have the schematic from Aeroelectric for the wigwag/ landing using one
switch 2-10. Can someone explain the need for the bridge rectifier. Also
is there a source somewhere for the individual switch schematics from
Carling.

Ken,
For what it's worth, here is the information on the two level switches we
bought for our Subaru back in 2009. I just dialed the phone number for

One other potential approach for your consideration... Belite
Electronics makes lightweight, low-cost instrumentation for ultralight
and experimental aircraft. They have developed a line of fuel sensors
and gauges that are pretty cool. You can go to
http://www.beliteaircraft.com, then go to their "electronics" page to
see all the gauges.
They sell capacitance fuel probes that are much lighter and less
expensive than the "commercial" ones, and will custom make them to your
length if desired. And they make several different single- and dual-tank
gauges (including the "Radiant" gauges that were featured in Kitplanes
and AvWeb feature articles).
But the one I really like is the "Low Profile Fuel Probe," which is a
MEMS-based "pressure-reading" transducer that effectively measures the
mass of the fuel in the tank. It can be purchased with a "fuel computer"
that calibrates and translates the fuel probe's output into 0.0 volts
(empty) to 5.0 volts (full), with intermediate calibration points at
1/4, 1/2, and 3/4 levels. It can also be purchased without the fuel
computer, for use with the "Radiant" fuel gauges that already have the
calibration/translation feature built in.
I plan to use the low-profile fuel probe (without computer - $100) and
the Radiant dual-tank gauge ($300) as the primary fuel level indicator
for the Bearhawk Patrol I'm building. I'll have sight glass tubes as a
backup, but they are harder to see from the pilot's seat. The two probes
and the gauge together will add only a few ounces to the empty weight -
probably about as much as the wiring from panel to wing tanks!
But that solution would probably be major overkill for your intended
purpose of monitoring the fuel level in the header tank. For that, I
would use the Low Profile Fuel Probe (with fuel computer - $200) and the
single-display Fuel Gauge ($80).
Some of you are probably be creative (and skilled) enough to forgo the
fuel computer or even the gauge, creating your own circuit to measure
the sensor output and decide when to turn on a "warning light" when the
level drops below your desired level. But me I'm too much of a
"newb" to even attempt such a thing, so I'll stick to a "professionally
designed" system.
