The Rotax engine has two CHT sensors preinstalled on the engine. One sensor is installed in the left
side cylinder head water jacket and one is on the right side.
Rotax recommends bare ¼” female Faston terminals (6.3x0.8 DIN 46247) to connect to the CHT probes.
You will need to add wires to the unpopulated connector pins.
The Rotax CHT probes are resistive sensors and should be connected to the DB-37 engine monitor plug
pins 22 (Tank 3) and 23 (Tank 4). When using the Rotax CHT probes you will not be able to have four fuel
tanks.
Once you have the sensors installed you will
need to configure the CHT sensor type to
“ROTAX CHT”
and configure the Temperature Ranges for your
engine.
