MONOBLOCK FERROPROBE MAGNETOMETRE Russian patent published in 2010 - IPC G01R33/02 

FIELD: measuring equipment.

SUBSTANCE: invention is related to magnetic measurements on movable objects, in particular to measurement of components and full vector of terrestrial magnetic field and magnetic course detection. Specified result is achieved by the fact that monoblock ferroprobe magnetometre, comprises three ferroprobes with mutually orthogonal magnetic axes and serially connected outlet windings and excitation windings joined to according outputs of switched excitation unit, amplifying-conversion unit connected to output winding of the first ferroprobe, generator, the first output of which is connected to frequency input of switched excitation unit, microcomputer with analog input connected to output of amplifying-conversion unit, and input of current consumption mode control connected to its first control output, and device for control of demodulator, the first and second outputs of which are connected accordingly to the first and second control inputs of phase-sensitive demodulator of amplifying-conversion unit, the first and second inputs of which are connected accordingly to the second and third outputs of generator, and the third input is connected to the second control output of microcomputer, input of clock frequency of which is connected to the fourth output of generator, and the third control output is connected to control input of switched excitation unit.

EFFECT: expansion of functional resources and improved accuracy of magnetometre by elimination of electromagnetic noise effect.
