FIELD: bridge units measuring resistance and reactance. SUBSTANCE: bridge unit includes current stabilizer 1, voltage inverter 2, resistors 3, 4, 5, 6. Balance condition of bridge unit is described by expression KR1R3= R2(R4- KR3-KR1), where K is transmission coefficient of inverter, R1, R2, R3, R4 are resistances of resistors of bridge unit. EFFECT: increased noise immunity and registration linearity of measured parameter in wider measurement range. 3 dwg
