P-Mag Operating Temperatures

[GalinHdz]

Does anybody know of available temperature sensors to easily monitor P-Mag temperatures on a DYNON SkyView EMS?

I installed a p-mag in my Giles in winter with a temp sensor attached to it. Recently, when the temp. on the ramp reached 90-95F, i observed that the p-mag case temperature shot up to 200F briefly after shutdown. I wonder what it is going to be when the ramp temperature reaches 100-110? Their temperature limitations are RIDICULOUS. I guess now I'm out of warranty because of that stupid temperature sticker. The temperature never exceeds 100-100 in flight.

What sensor are you using and how are you displaying the temperature?

The cheapest e-bay sensor, like this

Ok but I am looking for something more permanent and displayable on my SkyView.

If you order an Engine Bridge EI it will display all the info (internal temperature, advance angle etc..) on your Dynon or other digital EMS. You wont read this on their web site because it is a new capability and they have not changed the web site yet. The newer version also lets you make adjustments from any smart phone

The price is going up when they get around to updating their website, so I would order soon if this is the route you choose to go.

While not exactly what you are looking for, the Dynon EMS system comes with a carbuerator thermocouple to monitor carb temps for icing. I used that to monitor the Earthx battery temperature in my RV-7. It is mounted on the firewall directly above the battery.

You could mount it next to the P-Mag. It would not give you internal temperature but would give you a pretty good indication of the case and surrounding area temps.

It would display carb temp on the EFIS but you would know what it really is indicating.

Not a bad idea. I can change the displayed sensor name and call it PMagTemp. My question would be how to attach it to the PMag so it provides a "good enough" indication of case temperature not just the surrounding air temp.

I used aluminum tape to secure it to the firewall. It?s been there for over a year without coming off. The thermocouple is small and weighs next to nothing.

Got any photos of the install?
