FIELD: electric measuring equipment engineering, possible use for measuring power of constant and alternating currents, electric voltages and resistances.
SUBSTANCE: claimed device for measuring electric values contains bimetallic spiral, onto ends of which measuring contacts are applied for its connection to electric circuit being controlled and an amplifier, connected by output to registration device, object and support fiber coils, optically matched through coherent light source and photo-receiver into fiber-optic interferometer, where output of photo-receiver is connected to input of amplifier, and object fiber coil is applied onto bimetallic spiral with tightness. Object fiber coil may be applied onto bimetallic spiral by means of glue. Support fiber coil may be positioned between coils of bimetallic spiral near the object fiber coil. Registration device may be made in form of impulse counter of photo-current value meter. Claimed device may additionally contain phase-shifting device, positioned near one of fiber coils.
EFFECT: production of optical signal at output of measuring device, parameters of which signal are proportional to electrical value being measured.
