Hastemåler

Hastemåler is a Norwegian term that translates to "speed indicator" or "speedometer." It refers to an instrument used to measure and display the speed of a vehicle. While the most common application is in automobiles, hastemålere are also found in other forms of transportation such as motorcycles, trains, and aircraft.

Historically, early hastemålere were mechanical devices. These often utilized a spinning magnet connected to the vehicle's drivetrain, which would deflect a needle on a dial through magnetic force. Modern hastemålere, however, are predominantly electronic. They often work by sensing rotational speed via sensors on the wheels or transmission, or by using GPS technology to calculate speed based on the vehicle's position over time. The data is then displayed digitally or on an analog-style gauge within the vehicle's dashboard.

The primary function of a hastemåler is to inform the driver of their current speed, which is crucial for obeying speed limits, ensuring safe driving practices, and for accurate timekeeping on journeys. In many countries, a functioning hastemåler is a legal requirement for vehicles. Beyond its basic function, some advanced hastemålere may also display other related information such as trip distance, average speed, or even offer warning lights if a certain speed is exceeded. The term "hastemåler" specifically relates to this measurement and display of speed.
