Given its name, the function of a speed sensor from Sensor Solutions is quite self-explanatory; they measure the speeds of specific objects. First created to determine how fast a ship was moving, sensors used to consist solely of a piece of rope with knots tied in it. These rudimentary devices were then thrown over the sides of the ship, and the number of knots it was traveling was ascertained in a far more literal sense. Over time, though, more advanced sensors were needed to compensate for rapidly improving technology. This led to the implementation of magnetic sensors.
Though the magnet is an important part of the device, it is the electrical current, which surrounds it, that is responsible for its capabilities. The current produces an event known as the Hall effect, and this is what determines the speed of a given object.
The definition of the Hall effect is a longwinded one, but its explanation can be boiled down to the way electrical currents behave in the presence of iron or steel. These objects are types of ferrous metal, and when they come into contact with the current, they disrupt it. This disruption can then be transferred along wires and displayed on a speed gauge.
A speed sensor can be used on gears for this particular application. As the gears turns or spins, each tooth of the device is detected by the magnet. This causes the electrical current to be effected, and pulses to be sent out. The faster the gear spins, the faster the pulses are sent out and measured by the speed gauge.
There has been much advancement since the days when a speed sensor was nothing more than a rope with knots. As technology progressed, the need for more accurate speed measurements became greater. The employment of magnets allowed such needs to be met. By taking advantage of electrical currents, they can easily provide people with valuable information, which can then be used to foster even greater levels of technological innovation.
