sincronizzatori

Sincronizzatori, often referred to as synchronizers or synchros, are electromechanical devices used primarily in aviation and marine applications to indicate the rotational speed of an engine or other machinery relative to a reference speed. They typically consist of a transmitter and a receiver. The transmitter is coupled to the engine whose speed is being monitored, and it generates an electrical signal that varies in proportion to the engine's speed. This signal is then sent to the receiver, which is usually located on the instrument panel. The receiver, which is connected to a stable reference signal (often from a master oscillator or another engine in a multi-engine aircraft), interprets the incoming signal from the transmitter and displays the speed difference.

The primary function of a sincronizzatore is to help pilots or engineers maintain the desired speed relationship between multiple engines or between an engine and a reference. In multi-engine aircraft, sincronizzatori help ensure that all engines are running at the same speed, which reduces vibration, improves fuel efficiency, and enhances overall performance and safety. The display on the receiver usually indicates whether the monitored engine is running faster, slower, or at the same speed as the reference. Modern aircraft often use more sophisticated digital systems for engine speed monitoring, but the principle of comparing speeds remains the same. Sincronizzatori are also found in other contexts where precise speed matching is critical.
