Help with EGT Probe and a Suggestion on Fire Extinguisher

[GAdams]

I know from first hand recent knowledge that a type K does not work with the type E old style gauge we have in our aircraft. The reason is the value of the signal is stronger in a type E than a type K. A type E system must be entirely type E. The problem is the probe, the wiring and the gauge must be the same. That also applies to the K. No mixing of systems. Try this link for further details. Perhaps I misinterpreted the information. https://alcorinc.com/index.php/troubleshooting/

Correct. Not an expert but recently did a little "learning" while thinking about replacements for my gauges. There are basically two types of thermocouple wires/systems. Type K and Type E. The systems are not interchangeable. Since I put in a "K system", everything was replaced from exhaust to panel.

I took the easy way out and just replaced it all. Stuff for the K wire seemed easier to get.

Note that thermocouple wire is a specialized type of metal wire alloy and not your typical stranded variety. The probes have to be compatible with the wire/system you use.

Long term plan is replace everything with modern engine monitoring system
