Speed Sensors Then and Now

Author: Rosa Telipten

Ever since people first climbed into a moving vehicle to bring those who have wanted to know how quickly they moved at. The first speed sensors that were used to calculate the speed of movement was a rope with a series of knots to it. He was thrown overboard from a moving ship in ancient times and counted the knots in which floated to determine how many knots the ship was traveling at.

Knots still used

A speed ships is being calculated in knots and the phrase is still used, however, a long rope that was replaced by a more precise mechanical speed sensor. Al same time, speed sensors, ground-based vehicles have been many advances as well.

Cable systems old style

For decades, the speed sensors in ground vehicles were connected to cables that ran to meters that he told the driver the speed that the vehicle was traveling a. While it is the best that technology had to offer in that time, this type of cable system had its limitations.

Limitations of the cables

For example, the size of the tire of a vehicle could have an effect on the actual speed that was recorded on the meter on the dashboard. The larger the tire, slower the speed at which shows and smaller tires in turn resulted in a higher speed is shown as having made the number of RPMs the wheel in a given distance.

Advanced Speed Sensors of Tomorrow

ABS or antilock braking systems have pioneered the use of Magnetic speed sensors that do not use cable to transmit the speed to be detected in one source. These new high-speed sensor technology have enabled systems much more accurate and reliable complex to be used in vehicles today. Even now, the development engineers with vision are working to bring new types of speed sensors to be used in advanced vehicles of tomorrow.
