Hollow coils in industrial sensors are a common sensor component mainly used for measuring magnetic fields or currents. It is composed of an iron core or high magnetic material wound around a coil. When a current is applied to the coil, a magnetic field is generated, and the magnitude of this magnetic field is proportional to the current in the coil.
Hollow coils in industrial sensors are commonly used in current sensors, magnetic field sensors, position sensors, etc. For example, in a motor control system, the position and speed of the motor can be determined by measuring the magnetic field strength of the motor winding; In the power system, by measuring the magnetic field strength of transmission lines, the current magnitude and direction of the lines can be detected.
Hollow coils of industrial sensors have the advantages of high sensitivity, precision, and reliability, and are therefore widely used in fields such as industrial automation, power electronics, and motor control. Meanwhile, with the continuous development of technology, the size of hollow coils is getting smaller, the accuracy is getting higher, and the performance is becoming more stable, providing a more reliable guarantee for industrial automation control.
