TRANSDUCER OF ELECTROSTATIC FIELD Russian patent published in 1994 - IPC

FIELD: information and measurement technology. SUBSTANCE: transducer has additional calibrator made of electret material. Transducer body is made of ferromagnetic material. All power members of transducer drive are installed directly on body. EFFECT: higher measurement accuracy, compensated variation of conductance of transducer design members caused by variation of environment conditions, excluded effect of external permanent magnetic fields with simultaneous more effective use of power potentiality of magnetic system members provided by transducer design. 2 dwg
