MAGNETIC FIELD CONTROLLER Russian patent published in 2023 - IPC G01R33/07 

FIELD: measuring technology.

SUBSTANCE: invention relates to meters of induction of a constant magnetic field on the Hall effect. The Hall effect magnetic field controller comprises the power supply of the electromagnet; means for measuring the electromagnetic induction of a constant magnetic field on the Hall effect, including a thermostat with a temperature sensor and a Hall sensor; calculation and control devices associated with the devices for measuring electromagnetic induction and the electromagnet power supply, including a current source for the Hall sensor and an instrumental amplifier, an analogue-to-digital converter (ADC), a digital-to-analogue converter (DAC), a reference voltage source and a control signal level matcher and a microprocessor a computing device made in the form of a microcontroller, to which a Hall sensor temperature meter and a processor device for interaction with the operator are also connected.

EFFECT: stabilization of the magnetic field over long time intervals, simplification of control of the electromagnet power source.
