[ tæˈkɒməˌtər ]

Noun
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.

Etymology

The term 'tachometer' originates from the Greek words 'tachos', meaning speed, and 'metron', meaning measure. It was first utilized in the early 19th century to describe devices that measured the speed of rotation in machinery. The introduction of connected automotive technologies further popularized its use, especially in motor vehicles, where drivers needed to monitor engine performance effectively. Over the decades, tachometers underwent significant technological advancements, transitioning from simple mechanical designs to advanced electronic systems capable of providing precise readings and integrating with other automotive diagnostics. Today, tachometers are essential in various industries, ensuring machinery runs efficiently and safely.
