My airplane has the Westack capacitance fuel probes and I am trying to figure out how much power two units would consume and if I can use the Dynon Skyview PIN 15. The instruction sheet I found online (attached) discusses the installation of the probes however it is really lacking on electrical hookup. .. Cheers!!! Bill Hunter ________________________________ Message 4 _____________________________________ Time: 11:01:11 AM PST US Subject: AeroElectric-List: Re: WestTack (Westberg Manufacturing) Fuel Probe Power Consumpti From: "rampil" The trade name is Westach, not WestTack Capacitive fuel level probes are pretty much passive devices that do not consume power (aside from perhaps a tiny amount through dielectric leakage) An RF voltage is applied to the probe and the capacitance is measured across the electrodes. There is no polarity to these electrodes and so there is really nothing to say about how to hook it up, the two wires go into the monitor box. The issue of compatibility is one of measurable range of capacitance in the measuring box, most are adjustable, maybe not all. The capacitance of the probe in fuel is a function of probe geometry and immersed level of fuel (assuming you never switch to auto gas). Your best bet is to call dynon and ask if their box can adjust to the Westach probe. -------- Ira N224XS Read this topic online here: http://forums.matronics.com/viewtopic.php?p=469355#469355 ________________________________ Message 5 _____________________________________ Time: 12:19:35 PM PST US Subject: AeroElectric-List: Re: 12V Batteries From: "johnbright" How about electrically dependent RV-6A, IO-360, 8.5:1, SDS EFI/EI, Z-13/8? -------- John Bright, RV-6A, at Finish Kit Continental Titan IOX-360, 8.5:1, vertical sump, SDS EM-5 EFI and EI, injectors in heads.

If it was such a bad device, why in the heck were you flying behind something depending on it? Why isn't there an AD requiring removal? Yes, there were some issues with the dual mag when it was first introduced, both developmental and caused by mechanics unfamiliar with its specific needs. That is way in the past. There are numerous magneto shops that do quality overhauls of dual mags and know what is needed. PMA parts suppliers make most of the needed replacement parts. Properly installed and maintained, the dual mag is at least equal to the Slicks you suggest, perhaps better in terms of reliability. There are valid reasons to chose to change to individual mags, that have little to do with maintenance or cost. Parts are available within normal aircraft pricing. Slick mags may be cheaper than Bendix to purchase, but they will cost you more in the long run, because after the first overhaul, they are not economical to do subsequent overhauls. Reliable? compared to what? Certainly not more reliable than the comparable Bendix models. A vast majority of mechanics will choose Bendix over Slick any day. Need less maintenance, need less parts replaced, and deliver a hotter spark. Before TCM Bendix dropped its support for the dual mag, Lycoming charged typically $2500 to supply an engine with two single mags when the core engine had a dual mag. To make the changes needed, he is probably looking at similar or greater costs. Especially with shipping down under. Meanwhile, it is likely that by the time his mag needs an overhaul, there will be one or two electronic replacements available.

With both radios attached, one will be transmitting into the final amplifier of the other, in parallel with the antenna. It might work if you remove the non-transmitting radio and attach a 50-ohm terminator in its place (which obviously defeats the purpose of the installation). Otherwise impedance will probably not be seen as 50 ohms by the active transmitter, SWR will likely not be very good, and you risk damaging the non-transmitting radio. Also, from the data sheet you attached, see the Maximum Ratings table at the upper left corner: "Power input (as a splitter): 1W" -and- "Permanent damage may occur if any of these limits are exceeded." Typical handheld RF transmit power is 3-5W and panel mount radios are typically rated around 8W in 14V aircraft and 16W in 28V aircraft. I don't think this splitter is intended for this kind of application, but rather as an instrumentation tool, or as a means to connect two receivers to one antenna. I suspect the 1W rating allows some overhead if an active (amplified) antenna is used.

Um, yeah, like I said... Ever hit the "submit" button and shortly regret it? OK, ignore the bit about one radio transmitting into the other. After reading an application note about splitter/combiners on Mini-Circuits' website, it's obvious these things offer isolation between the ports. So, one radio on port 1, one radio on port 2, antenna on the sum port. Power handling is another issue. The unit you have isn't rated for the power levels we're talking about. It looks like they have plenty of units that are, however. Eric With fingers crossed, tapping "submit" again... now!

THANKS!!! ________________________________ Message 14 ____________________________________ Time: 05:20:05 PM PST US Subject: Re: AeroElectric-List: P-leads From: Kelly McMullen Just because TCM dropped support for the mag does not mean it doesn't exist. It also does not mean that in the USA cost is significantly different than maintaining two separate mags. Disaster for maintenance implies unexpected failures in my book. Examples done by quality mag shops in the US are not prone to failure before 500 hours, and are not out of sight on overhaul cost. Some engines they are used on, such as the O-320-H2AD, there is no single mag model made, you cannot convert. Seems you could do an exchange with a US magneto shop for a lot less than what you are quoting. I'm not a fan of the dual head magneto, but it isn't nearly as bad as you portray. Your Slick overhaul, if the price is for both, you can't achieve that in the US, and overhaul at 1000 hours will exceed the cost of new. In most any turbo-charged application the Slicks won't make 500 hours. In the US overhauling a Slick will cost as much or more than overhauling a Bendix.

A splitter doesn't do the same thing as a switch box (hence, the different names). A splitter will send an antenna's signal to two *receivers*. The switch box (cheesy though it is) actually switches the antenna between two radios. Because it switches, it's ok to attach both *transceivers* to the box. Only one gets connected at a time. If you connect two transceivers through the splitter to one antenna, then one transmitter will attempt to transmit directly into the other's receiver. Not a good plan.
