ELECTRODYNAMIC VOLTAGE, CURRENT AND POWER COMPARATOR Russian patent published in 2009 - IPC G01R17/08 

FIELD: physics.

SUBSTANCE: comparator contains mobile system in the form of horizontal beam. The mobile reels of two electrodynamic transformers are strengthened along the edges of the beam, and fixed coils are rigidly joined to the comparator basis. One of the loops of the fixed coils is executed mobile with possibility of distance change between the loop of the mobile reel and the loop of the fixed coil. The devices of beam fastening provide gyration of the beam and stability to traversal oscillations. The target signal from two photoelectric transformers develops and amplifies. Jack of the opposing moment of extensions that provides increase of its sensitivity and accuracy is entered into the comparator.

EFFECT: increase of sensitivity and accuracy of comparator.
