DEVICE FOR MEASURING OF ELECTRICAL CONDUCTANCE OF LIQUID MEDIA Russian patent published in 1998 - IPC

FIELD: electrical engineering. SUBSTANCE: device has two toroidal magnetic 1 of voltage transformers, four magnetic cores 4 of current transformers, recorder 15, sinusoidal voltage generator, 8, two amplifiers 9, three summing amplifiers 10, 11, comparator 14, setting unit 13, and unit of switches 12. Magnetic cores 1 have field winding 2 and auxiliary winding 3. Magnetic cores 4 have measuring windings 5. Voltage transformers are of identical construction, and they arranged symmetrically. Current transformers are also identical. They are positioned symmetrically in pairs. Magnetic cores of current and voltage transformers are located in mutually perpendicular planes. EFFECT: higher measurement results. 2 dwg
