Nopeudensäätelevä

Nopeudensäätelevä, often translated as speed limiter or governor, is a device or system designed to prevent a vehicle or machine from exceeding a predetermined maximum speed. These devices are employed in various applications to enhance safety, efficiency, and compliance with regulations.

In automotive contexts, speed limiters are common in commercial vehicles such as trucks and buses. Their primary purpose is to enforce speed limits set by regulatory bodies, thereby reducing the likelihood of accidents caused by excessive speed, especially in challenging conditions. This also contributes to fuel economy and reduces wear and tear on the vehicle. Passenger vehicles may also be equipped with speed limiters, particularly in certain markets or for specific models, often as a feature to ensure responsible driving.

Beyond road vehicles, speed limiters are found in industrial machinery, elevators, and even recreational equipment like go-karts. In industrial settings, they protect both personnel and equipment by preventing dangerous operating speeds. For elevators, a speed governor is a critical safety component that activates emergency braking systems if the elevator car descends or ascends at an unsafe speed. The implementation and stringency of speed limiting technology can vary significantly based on the application and the jurisdiction.
