FIELD: the invention refers to engine manufacturing particularly to control systems of aircraft engines and may be used for measuring revolutions of a turbine.
SUBSTANCE: the arrangement has an inductor, a bracket with a sensor of rotational velocity SRV-250 installed on it. The inductor is fulfilled split and is fixed on the socket connecting the power turbine with a gas supercharger and the sensor of rotational velocity is fixed with the aid of the bracket on the body of the shaft of the free power turbine.
EFFECT: eliminates necessity of dismantling of a free power turbine of an aircraft engine at its exploitation.
