A variety of devices, industrial machinery, and automobile processes rely on gear tooth sensors to sense position and speed of a gear. Using these sensors allow the motion of gear teeth to be converted to an electrical impulse. While mechanical systems designed to measure a gear’s position and speed tend to become less effective due to wear over time, a gear tooth sensor that uses magnetic induction is not subject to these disadvantages.
Many sensor systems used for gear teeth use the Hall effect. Discovered in 1879 by Edwin Hall, the Hall effect involves the creation of a difference in voltage across a material perpendicular to the movement of the current and magnetic field. A Hall effect sensor can measure the position or proximity of an object by detecting the magnetic field.
A Hall effect gear tooth sensor works more effectively and accurately than a mechanical device because it does not come in contact with the gear itself, and therefore places no drag on the gear.
Gear tooth sensors have several applications. Because they have the ability to detect miniscule changes in a magnetic filed, these sensors are often used near very small gears or motors. For example, they are used in industrial processes to measure direction or speed of a shaft or gear. The information from the sensor can be transmitted to a digital or analog monitor or a computer. Many sensors contain a magnet that will switch when placed within a certain distance of a ferrous material, which would include a gear tooth.
Automobiles also contain sensors to measure the location and speed of gear teeth. Processes such as anti-lock braking systems (ABS) require these sensors to recognize unusual changes in speed of a wheel. Additionally, systems in vehicles that meter airflow contain a gear tooth sensor.
