DEVICE FOR MEASURING OF VARIABLE MAGNETIC FIELD INDUCTION Russian patent published in 1998 - IPC

FIELD: magnetomeasurement technology. SUBSTANCE: inductive pickup is used for measurement. Pickup signal is supplied to inputs of amplifiers having different gain factors and integration function. Outputs of amplifiers are connected to inputs of comparators and multiplexer. Depending on level of signal coming from pickup device output is supplied through multiplexer with signal from output of amplifier the gain factor of which corresponds to pickup signal level most of all. This or that output of amplifiers is connected to device output due to tracking of signal levels by means of comparators, the outputs of which are connected to multiplexer address outputs through priority decoder. EFFECT: wide range and high accuracy of magnetic induction formation. 2 dwg
