Backup Oil temp,pressure gauges

[ArtVandelay]

For those who have upgraded to a certified engine monitor, did any of you keep or added secondary oil gauges so in case your EM fails (or sensors), you are still legal? Anyone have an oil pressure sensor fail and wish they had a backup? Do you care extra sensors just in case?

I did not, and don't worry about it. Most gremlins will be installation-related, and should be identified and fixed early on/quickly. My EDM-900 has been great for 2+ years except for a faulty connector crimp (my fault).

Ideally I’d like to get rid of my backup gauges because of the extra failure points, fuel lines past the firewall, and panel clutter. You could probably fine some cheap used oil pressure sensors to have in your kit if one did fail.

I have primary backups for the RPM, fuel pressure and MP. I moved from mechanical fuel senders to the CiES senders but still only have one source for the fuel tanks, oil pressure and oil temperature.

The way I look at it, even if I had the mechanical gauges, if the oil pressure gauge failed I would still be down. With the EI primary backups for MP, RPM and fuel pressure, I have at least some redundancy that would let me continue to fly if the JPI failed for those gauges. The downside to the JPI is the “all in one basket” situation. In my case, oil pressure, oil temp and fuel gauges are the risk.

And I will add that the failures I had on the JPI were in fact the MP and RPM not displaying correctly. I had to send it back for those issues and even with the EI primary gauges for them, I wasn’t legal and didn’t fly.

All my issues were with the transducers being dirty, I try to clean them yearly now since a couple failures last yr. At least it's a cheap solution.

Since you like the EI gauges, and I’ve seen your panel so I know price is no object, I’m surprise that you don’t have this one:

I replaced the old EGT/OAT gauge and replaced with the UBG-16 EGT/CHT/FF/OAT/VDC. I kept the old steam gauges because they were easy to read, reliable and in my front view.

This thread got me to thinking....

What if my back up engine instruments were a skyview....    And it was attached to a flexible shaft (not installed in the panel) like my tablet.    And I sent the data to the skyview display over a wireless connection using foglamp?

It would be placarded "standby only. not certified for flight"

that would be cool.

I have an edm830 and have already used MP reading against the oem gauge to verify in fact there was a leak and not just wonder if it was the sensor.   Turned out to be a broken flare on the reducer b-nut at the baffle.    I see value in having redundancy for that reason.  Two in agreement confirms an actual issue.

I put the JPI 830 in a year ago. Left the old stuff in though, I like to look at steam gauges as well, kinda makes me feel like a real pilot not a systems manager. I do love the data though! You'll enjoy the EDM one of the better investments for a healthy engine
