TRANSDUCER OF LINEAR MOVEMENTS Russian patent published in 1995 - IPC

FIELD: measurement technology. SUBSTANCE: transducer of linear movements has case, contact lug and withdrawable rod spring-loaded relative to case, electromagnetic calibrator which ferromagnetic armature is connected to contact lug of transducer. Withdrawable rod of transducer carries ferromagnetic core which position determines inductive resistance of two windings of transducer connected differentially. Contact lug is located in reversible bearing and has mushroom-shaped head interacting with free butt of rod with its flat part. Coupling between contact lug and calibrator armature is accomplished with capability of control over distance between them which provides for control over both electrical and mechanical part of transducer and leads to enhanced convenience of its use. EFFECT: simplified design, increased reliability and enhanced convenience of use. 2 cl, 3 dwg
