DEVICE FOR CONTROL OVER INTENSITY OF DC AND AC MAGNETIC FIELDS Russian patent published in 2016 - IPC G01R33/07 

Abstract RU 2572294 C1

FIELD: instrumentation.

SUBSTANCE: invention relates to instrumentation, particularly, to AC and DC magnetic field intensity control device. Claimed device comprises Hall transducer. Signal of the latter is fed via amplifier to frequency correction link input connected to two-position switch. Output of position I is connected with DC threshold element while output of position II is connected via amplitude detector with AC field threshold element. Threshold elements are connected with warning device and LED alphanumeric display. External supply battery charge level controller is also connected to said display.

EFFECT: continuous control, simplified warning of personnel about intolerable field intensity level.
