New Kavlico Pressure Sensors....

[mikehoover]

Dynon's announcement of the new Kavlico pressure sensors has got me to wondering if I should plan ahead in my wiring. I have not yet closed up my wiring (Vans RV-9A).

The newsletter says the new Kavlico sensors will require an additional wire to provide the sensor a 5 volt source. So, I am trying to figure a good solution to prepare for future upgrade to the new sensors.

Should I run a 5 volt wire from my main buss via and convert from 12 v via some sort of regulator?

Is there a spare 5 volt wire from the EMS that would accommodate the sensors?

I expect I would be replacing only the oil pressure and fuel pressure sensors at some point in the future (ie, as/if they fail).

I could run a 5 volt wire to the FWF area and stub it out now and tap into it in the future.

Comments/suggestions?

I have a Lycoming O-320 carbureted installed.

Thanks!

The +5V that the Kavlico sensors require can be sourced from the EMS.

Pin 18 is +5V on the 37-pin connector on the EMS-D10, EMS-D120, FlightDEK-D180, and SV-EMS-220.

This +5V line can be shared with other sensors.

Hi Dynon,
I have a 0-375 Lycoming with the Skyview system. I would like to change the fuel pressure sensor to one of the new ones. Do you have a part number yet? Will you offer them through your store?
Thanks,
Larry

Full details of the Kavlico sensors - P/Ns, pricing, etc. AND being able to buy them, will be available on the Dynon website on January 2, 2011. Our sales team will also be able to take orders via email, website, and phone at that time (but not before).

Do the Kavlico sensors come with the connector?  If not do you have the p/n for it?

 

[dynonsupport]

They come with the connectors and about 5" of wire.

Is there a good reason to switch to these sensors if I've already installed the previous ones?  What is the life expectancy of the old non-solid-state ones?

thanks,

Tough question to answer with numbers (ie, there's no life expectancy data that we can pass along).

But anecdotally, the legacy sensors work quite well for most people. Because of their mechanical nature, some people have found that they do tend to develop some "sticktion" over time, but not everyone experiences this. They're also not particularly great at the low end of their pressure ranges, period.

In short, there are literally thousands of them out there in our customer-base, and they aren't "bad" sensors per-se, but, we were seeing the themes above, and we finally found a different sensor that does a better job that isn't hundreds of dollars.
