FIELD: transport; shipbuilding.
SUBSTANCE: device contains magnetoelastic torque transducer consisting of two magnetoelastic converters located at opposite sides of propeller shaft and made with test coils. Transducer is capable of measuring mechanical stress caused by torsional oscillations and constant component of torque. There is compensation circuit of zero signal and automated remote control system for main engine of vessel's power plant. Apart from it, device has synchronous detector, lower frequencies filter, upper frequencies filter, and threshold devices.
EFFECT: increase of reliability and efficiency of vessel's power plant at expense of prevention of operation of diesel in sphere of mechanical stress from torsional oscillations exceeding preset value and its protection from overload.
