    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. -------- Joe Gores Read this topic online here: http://forums.matronics.com/viewtopic.php?p=465833#465833

    Looking up the chemical resistance of the plastic from which this sensor is manufactured it appears to have excellent resistance to all forms of gasoli ne, benzine, astm fuels and astm oils as well as ethylene glycol and brake flui d.. So yes, it would appear suitable for use in a header tank. However a query to the manufacturer requesting their opinion would yield the safest answer. Te ll them the application is for level in a fuel storage tank NOT an aircraft he ader tank.=F0=9F=98=84 Bob McC > ---------- Original Message ---------- > From: Ken Ryan <keninalaska@gmail.com> > Date: February 6, 2017 at 10:19 AM > > Can you guys tell me if this (153064) would be an appropriate sensor for > my 5 gallon header tank to turn on an LED if the tank is not full? > > sensor: > http://ecatalog.gemssensors.com/ecatalog/singlepoint-level/en/153064 > > LED: > https://www.aircraftspruce.com/catalog/elpages/lstestled.php?clickkey=4 85496 > > sensor catalog page: > http://www.gemssensors.com/level/Single-Point-Level-Switches/Electro-opti c/Engineered-Plastic/~/media/GemsNA/CatalogPages/ELS-1100HT-cat.ashx > > Thanks, > > Ken >

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 Bob . . .

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. -------- John Evens Thorp T-18 N71JE (built &amp; flying) Kitfox SS7 N27JE (building) Read this topic online here: http://forums.matronics.com/viewtopic.php?p=465845#465845

    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.

    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. Jim Parker
