kiirusmõõtjaga

Kiirusmõõtja, commonly known as a speed measuring device, is an instrument used to determine the velocity of an object. These devices operate on various principles, depending on their intended application. In the context of road vehicles, a kiirusmõõtja often refers to a speedometer, which is a standard component of most cars and motorcycles. This type of device typically measures the rotational speed of the transmission's output shaft or wheel axle and converts this into a linear speed reading, usually displayed in kilometers per hour (km/h) or miles per hour (mph).

Beyond automotive applications, kiirusmõõtjad are used in a multitude of fields. For instance, radar guns are employed by law enforcement to measure the speed of vehicles from a distance using the Doppler effect. In aviation, airspeed indicators measure the speed of an aircraft relative to the surrounding air. Scientific research utilizes various types of kiirusmõõtjad, such as anemometers for wind speed measurement or laser Doppler velocimeters for precise flow velocity determination in fluids. The underlying technology can range from mechanical gears and cables to sophisticated electronic sensors and signal processing. The accuracy and range of a kiirusmõõtja are critical factors that determine its suitability for a given task.
