Every day, countless machines and devices rely on the precise measurement of speed to function optimally. One of the unsung heroes of this task is the Hall Effect Speed Sensor. This sensor, rooted in a 19th-century discovery, plays a vital role in a myriad of modern-day applications.
At its core, the Hall Effect is a phenomenon wherein an electrical current, passing through a conductor in a magnetic field, induces a voltage perpendicular to both the current and the magnetic field. This was first discovered by Edwin Hall in 1879, laying the foundation for the development of Hall Effect Sensors.
The process begins with the presence of a magnetic field. As this field fluctuates, it induces the Hall voltage in the sensor. This analog signal is then processed and converted, leading to an output that directly corresponds to a specific speed. The placement of the magnetic source, like a rotating gear, can vary the magnetic fields and thus the output signal.
What sets these sensors apart?
From cars to computers, these sensors find utility everywhere:
While optical sensors use light and mechanical sensors rely on physical movement, Hall Effect sensors use magnetic fields. Each has its advantages, but the Hall Effect often stands out due to its durability and accuracy.
As technology evolves, so do these sensors:
