Propeller Revolution Transmitter

A Propeller Revolution Transmitter is a device used in shipboard alarm and signal systems. It is part of the supply class Shipboard Alarm And Signal Systems, which falls under the supply group Alarm, Signal And Security Detection Systems.

The Propeller Revolution Transmitter is responsible for measuring and transmitting the revolutions per minute (RPM) of a ship's propeller. This information is crucial for monitoring the performance and efficiency of the propulsion system.

The transmitter typically consists of sensors that detect the rotational speed of the propeller shaft and convert it into electrical signals. These signals are then transmitted to the ship's control system or display unit, where the RPM data can be monitored by the crew.

By continuously monitoring the propeller revolutions, the ship's operators can ensure that the engine is running at the desired speed and detect any abnormalities or malfunctions in the propulsion system. This helps in maintaining the ship's performance, fuel efficiency, and overall safety.

Overall, the Propeller Revolution Transmitter plays a vital role in shipboard alarm and signal systems by providing real-time information about the propeller's RPM, enabling efficient operation and maintenance of the ship's propulsion system.
