DEVICE FOR REPRODUCING CHANGING MAGNETIC FIELD WITH MODELS Russian patent published in 2005 - IPC

FIELD: magnetic measurements.

SUBSTANCE: device for reproducing changing magnetic field with models has voltage increase speed restricting system, amplifier, two inductance coils, resistor, rectifier, memory unit, rectangular-shaped oscillator, 3 digital-to-analog converters, two counters, three registers, five analog switches, six reference voltage sources, seven comparators, NOT gate, 12 summing amplifiers, four analog memorizing units, analog multiplier, two analog dividers, multiplexer, 4-OR gates, four D-flip-flops, four OR gates, four analog models, device for finding minimal value, magnetic intensity measuring channel, number of measured points set-point device and two priority coders. Time of measurement is reduced due to ability of reducing number of measured points of hysteretic curves at constant approximation of output data.

EFFECT: reduced time of measurement. 3 dwg
