varvtalsmätaren
A varvtalsmätare, often translated as tachometer, is an instrument used to measure and display the rotational speed of a shaft or disk. It is commonly found in vehicles where it indicates the engine's revolutions per minute (RPM). This allows drivers to monitor engine performance and avoid over-revving, which can cause damage.
The principle behind a varvtalsmätare can vary. Mechanical tachometers use a centrifugal governor system connected to
In industrial settings, varvtalsmätare are crucial for monitoring the speed of motors, turbines, and other rotating
