Egt (Exhaust Gas Temperature); One Piece Cht Probe Installed - Garmin G3X Installation Manual

14.3.2 EGT (Exhaust Gas Temperature)

Sensor Description – Type K grounded thermocouple probe with integrated clamp for mounting in an
exhaust pipe.
NOTE
If ungrounded thermocouples are used, the low side must be taken to a GEA 24/GSU 73
ground pin.
14.3.2.1 Engine Sensor Installation
General Installation Guidance – To maintain G3X Engine Indicating System (EIS) measurement
accuracy, thermocouple (TC) wire must be connected directly to the inputs of the GEA 24/GSU 73. If the
supplied sensor wires are not long enough to connect directly to the GEA 24/GSU 73, then Type K TC
extension wire must be used. To minimize risk of breakage, it is recommended that a high quality stranded
(as opposed to solid) thermocouple wire be used. TT-K-22S Type K thermocouple wire from Omega
Engineering is one such example of appropriate wire.
When using Alcor Type K probes, refer to Alcor EGT Installation Instructions (P/N 59180) for complete
installation details. Engine manufacturer's guidance should be consulted and followed for proper location
of EGT probes.
