tachometer
Measures rotational speed
A tachometer measures rotational speed, typically in revolutions per minute (RPM).
In vehicles, it displays engine speed on the dashboard, helping drivers know when to shift gears or avoid over-revving: The tachometer showed the engine redlining.
Industrial tachometers monitor machinery like turbines and motors.
