GEARBOX OIL TEMPERATURE SENSOR

This is a PTC (Positive Temperature Coefficient) sensor (1) located in the electro-hydraulic unit and integrated in the electrical wiring.The signal from this sensor is used by the control unit for managing the "SKT gearbox oil temperature safety" programme.

GEARBOX OUTPUT RPM SENSOR

This inductive sensor is located behind the electro-hydraulic unit opposite the reduction pinion ring gear teeth.

GEARBOX SHAFT INPUT RPM SENSOR

This inductive sensor is located near the electro-hydraulic unit opposite the input shaft cover references.The signal from this sensor is used by the control unit to recognize the gearbox input angular speed.
