CHT Ring vs Bayonet Probes

We supply both bayonet and ring type probes for our CHT instruments.

In some cases only the ring type probes may be installed on your engine (Continental O-200, O-300 and similar). To use the bayonet type probes your cylinders must have a thermowell that can accommodate the thermocouple.

If you intend to use the CHT instrument to fly by manufacturer published temperatures you must use the same probe type that correspond to the published temperatures.

In general ring type probes will read higher temperatures than bayonet types. This is due to the location of the thermocouple on the cylinder. With ring probes you will also notice a difference in temperature when using the top or bottom plug for attachment.
