In paper device for measuring of torque and rotational speed at the ship main drive propeller shaft transferred will be described.. This device connected to the power plant monitoring systemt. It may be used for continuous control of operating costs of the ship and for the choosing of safe and best engine operational parameters. It is possible to observe the actual point of engine's operational state marked against the mechanical characteristic chart. The limited, safe area of acceptable working points is displayed on the diagram as well. The presented torque meter has possibility to measure instantaneous fluctuations of the torque and engine rotational speed as a function of the shaft rotation angle. This is a piece of important diagnostic information for fast preliminary assessment of the load on a particular cylinder and of the quality of engine work.
