3D Helmholtz Coil
Closed-loop Control
The closed-loop control system for 3D Helmholtz coil includes a full set of automatic control of magnetic field. The system consists of a mounted Hall sensor, 3D coil-sets, high-precision power supplies, and the control PC. The power supply has its own built-in “continuous averaging” algorithm that allows it to perform full closed loop control. The controller implements closed loop control in combination with power supply and a Hall sensor using software. The control PC simply sends the desired field value - the controller will drive the power supply to maintain the field setting in a stable way. The magnet and power supply become a simple "set and move" system, relieving the control PC and the communications network of any ongoing control. The Helmholtz coils are equipped with a vertically adjustable platform to adjust the position of the samples.
