DEVICE FOR DETERMINATION OF CONTENT OF MAGNETITE IN IRON ORE

摘要

Device for determination of content of magnetite in iron ore relates to testing geophysical wells, walls of mine workings, ore in bulk and in transport tanks. Device has transmission coil connected to output of sinusoidal generator thjat is connected to first input of automated amplification controller, receiving coil connected through current amplifier to first input of synchronous detector with output connected to low frequency filter, programmable amplifier and source of support voltage. There additionally are included former of rectangular pulses and analog-digital transformer. Automated controller of amplification is with second input connected to source of support voltage, output of sinusoidal generator is connected to the second input of synchronous detector through former of rectangular pulses and low frequency filter is connected through programmable amplifier and analog-digital transformer to measuring block. Automated amplification controller is arranged by layout of current stabilizer. The device provides increase of accuracy of measurement.
