Adding EGT Probes

[ZK-SVH]

Hi there everyone.

I‘m installing Skyview HDX system on a Rotax 912 ULS. I have the EMS220 and the Rotax kit. The kit contains wiring and two probes.

If I want to install probes on the other two cylinders should I just buy two more probes and wire them to the appropriate pins on the plug? And for the wire extension should I get EGT extension wire? Is Type K thermocouple wire for directly connecting to EGT probes?

Thanks Peter

Hi Peter

check out the installation manual on page 7-43 and 7-45 it describes what is acceptable for extending the EGT sand CHT wires.

Yep, type K thermocouple to extend ; don't have a junction across a temperature change (ie firewall).

Can the wires on a stock CHT or EGT probe be shortened? I found this in the manual, "It is recommended to not cut the “armored” portion of the cable near the sensor end of the CHT or EGT sensors." but does this mean that they can't be shortened at all or to just not cut them so short that you get close to the sensor ends?

Also, it appears the builder of my plane used the brown extension wire for both the CHT and EGT sensors. Is this ok or is there a different extension wire for the CHT sensors?

Lastly (3rd edit ), what are the best connectors to use for sensor extensions forward of the firewall where there is likely to be a lot of oil residue.

Thanks!
