The CHT Bayonet probes are the threaded probes and are commonly known as ‘CHT Bayonet Probes’. These are typically used on Lycoming engines in aircraft.

Let us start with extending the CHT probes - most CHT probes available in the market feature cold-junction compensation. Cold-junction compensation means that the temperature of the cold junction of the thermocouple is measured (at the RDAC) and this temperature is used to compensate for ambient temperature with the small voltage readout between the two alloys at the thermocouple junction. For this reason, it is important that type-K extension wire be used for type-K thermocouples. You can use the same extension wire for ... Read more »
