A tachometer sensor translates a rotating object's speed into power output. It's a type of indirect measurement device that can be made in a variety of ways, including mechanical, electrical, magnetic, optical, and hybrid. Volvo Penta Tachometer Sensor (354671) is a mechanical or electrical instrument that measures rotation. When the spark plug fires, the ignition system sends a voltage pulse to the tachometer electromechanical part's output. The electromechanical component reacts to the average voltage of a sequence of pulses, demonstrating that the pulse train's average voltage is proportional to engine speed.
A vehicle's tachometer sensor allows the driver to pick appropriate throttle and gear settings for the driving conditions, as excessive use at high speeds might result in insufficient lubrication, which can harm the engine. It allows the driver to avoid overheating and surpassing the speed capabilities of sub-parts such as spring-retracted valves in the engine, resulting in unnecessary wear, permanent damage, and even engine failure.
