tachometer

[tæˈkɒməˌtər ]

Definition

Context #1 | Noun

mechanical device

A tachometer is an instrument used to measure the rotational speed of a shaft or disk. It is commonly employed in engines, vehicles, and machinery to provide an indication of the engine's RPM (revolutions per minute). By measuring the speed of rotation, tachometers help monitor the performance and efficiency of related systems. They can be either analog with a needle display or digital with numerical representations. This tool is essential for ensuring that engines operate within safe and efficient parameters.

Synonyms

RPM meter, revolutions counter, speedometer.

Examples of usage

  • The tachometer indicated that the engine was running at 3000 RPM.
  • Drivers rely on the tachometer to shift gears at the optimal speed.
  • The mechanic used a tachometer to diagnose the engine's performance issue.
