MAGNETIC FIELD CONVERTER Russian patent published in 1994 - IPC

FIELD: non-destructive control. SUBSTANCE: magnetic field converter has sweep unit, magnetic-sensitive unit made of n sensitive elements which has input connected with output of sweep unit and video-control unit. Control input of the latter is connected with output of sweep unit. Converter is also provided with n-channel commutator which has information inputs connected to outputs of magnetic-sensitive unit, address bars of commutator are connected to sweep unit. Input of video-amplifier of the converter is connected with output of commutator; output of video-amplifier is connected with input of video-control unit. Sensitive elements of magnetic-sensitive unit have to be sealed contact reed relay. Inductance coil is reeled upon glass bulb of each sealed contact reed relay. Some outputs of the coils are connected with common bar, the other outputs have to be address bar of magnetic-sensitive unit. Some outputs of sealed contact reed relays have to be outputs of the magnetic sensitive unit, the other outputs of the relays are integrated and intended for connection to voltage supply. EFFECT: improved precision of control; improved noise immunity. 2 dwg
