TRANSFORMER POSITION PICKUP Russian patent published in 1999 - IPC

FIELD: measurement technology. SUBSTANCE: transformer position pickup has immobile magnetic circuit with excitation and measurement windings, mobile magnetic circuit and additional mobile magnetic circuit. Mobile and additional magnetic circuits are manufactured in the form of two shafts. Shafts are kinematically intercoupled with the aid of two identical composite gears. Each gear includes ferromagnetic and nonferromagnetic parts. Joined parts are so oriented with respect to one another that they are always engaged by means of teeth having same length of ferromagnetic and nonferromagnetic sections. Such design of pickup makes it feasible to measure sum of angular movements of two objects. EFFECT: feasibility of measurement of sum of angular movement of two objects. 2 dwg
