What is the device used to measure the speed of a turbine?

Explanation:
Measuring how fast a turbine shaft is turning. The device used for this is a tachometer, which quantifies rotational speed, typically in revolutions per minute. Tachometers can attach to the shaft (contact) or sense speed without contact using optical or magnetic pickups. In turbine operation, knowing the RPM is crucial to ensure the machine runs within its design limits and to detect overspeed conditions that could cause damage. The other instruments measure different quantities: a barometer gauges atmospheric pressure, an anemometer measures wind speed, and a manometer measures pressure differences in fluids.
