MEASUREMENT OF SUPERCONDUCTING INCLUSIONS INTO HIGH-TEMPERATURE MATERIALS Russian patent published in 1995 - IPC

FIELD: measurement of electrophysical properties of superconducting materials. SUBSTANCE: device for realization of measurement has bridge of mutual inductance connected with input to A.C. generator and with output to synchronous amplifier which second input is coupled to output of reference signal of generator, unit of functional conversion having program of nonlinear dependence of output signal of amplifier on concentrations. Device also has solenoid into which bridge of mutual inductance is placed, controlled D. C. source linked to solenoid. Input of unit of functional conversion is connected to output of in-phase signal of synchronous amplifier and its output - to indicator of concentrations. EFFECT: enhanced authenticity of measurements. 3 dwg
