Have you ever been cruising down the road and pass a police officer? The first thing you are likely to do is slow down, regardless of how fast you were going, the next is to check your speed using the speedometer on your vehicle. Have you ever stopped to think about how some of the technology in our lives works though? I’m amazed to be typing on my laptop and sending up blog posts to space which end up on your google browser. How crazy is that? Yongchang has OEM speedometer for sale.
Speedometers are less high tech than you might think. They simply measure how fast your wheels are turning and does some math regarding how big your wheels are and calculates out how fast you are going. Police officers use radar to measure your speed which involves a laser beam that bounces off of your car and back to its source, thus telling the machine how fast you are moving. It’s obviously more complicated than that, but that is the gist of it.
The speedometer is part of the instrument cluster on your vehicle which displays important vehicle statistics such as speed, miles traveled, temperature of the vehicle, and fuel levels. The instrument cluster also is where you will find warning lights for your car.
The speedometer has two separate semicircles which contain a set of numbers. The smaller semi circle shows numbers in kilometers and the exterior semi circle typically displays figures in miles. As the hand of the speedometer sweeps through the circles, where it sits is the current speed of the vehicle.
