Question 207Electricity & Electronics - Assistant Engineer

The correct answer is C) Rudder angle indicator system. The rudder angle indicator system on a ship uses a synchronous transmission system to transmit the rudder angle information from the rudder to the indicator on the bridge or other control stations. This synchronous system ensures that the displayed rudder angle accurately reflects the actual position of the rudder, allowing the ship's officers to monitor and control the vessel's steering. The other options are incorrect because they do not utilize a synchronous transmission system. Turbocharger RPM, shaft revolution, and centrifuge RPM indicator systems typically use different types of transmission, such as electronic or mechanical, to convey the respective measurements.
