14.3.1.1 Lycoming and Continental Engine Sensor Installation

General Installation Guidance – To maintain 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. One such example of appropriate wire is TT-K-22S Type K thermocouple wire from Omega
Engineering.
When using Alcor Type K probes, refer to Alcor CHT Installation Instructions (P/N 59167) for complete
installation details. Engine manufacturer's guidance should always be consulted for proper location of
CHT probes. A finger sized loop should be provided to allow sufficient strain relief of the probe assembly,
and care should be taken to ensure that no chafing of the wires occurs.
