In modern electrical systems, accurate current measurement is of utmost importance for the stable operation of equipment, energy management, and safety assurance. Hall current sensors, as efficient and reliable current – measuring tools, are being widely used in various fields. Today, let’s take an in – depth look at Hall current sensors. I. Working Principle Hall current sensors operate based on the Hall effect. When an electric current passes through a conductor, a magnetic field is generated around the conductor. A Hall element placed in this magnetic field will generate a voltage proportional to the magnetic field strength, known as the…

When it comes to measuring electrical current, two of the most commonly used technologies are Hall Effect sensors and Shunt resistors. Both methods have their strengths and weaknesses, and the choice between them often depends on the specific requirements of your application. In this blog, we’ll explore the key differences, advantages, and limitations of Hall Effect sensors and shunt resistors to help you decide which is better for your current measurement needs. How They Work Shunt Resistors A shunt resistor is a low-resistance precision resistor placed in series with the load. According to Ohm’s Law (V = IR), the voltage drop across the resistor is proportional…

Imagine trying to understand the inner workings of a complex biological system, where the smallest particles, such as free radicals or metal ions, play a crucial role.
