HERMETICALLY SEALED DISPLACEMENT TRANSDUCER Russian patent published in 1995 - IPC

FIELD: electrical engineering. SUBSTANCE: hermetically sealed displacement transducer has two switching over hermetically sealed reed relays with breaking contacts-parts brought out to one side of cylinder of each reed relay placed in parallel to each other, permanent magnet magnetized longitudinally and installed between specified relays perpendicular to their longitudinal axes on rotating rod. Size of poles of permanent magnet longitudinal of its controlled displacement is determined as d > 4·R·tg(A/2), where D is size of poles of permanent magnet; R is length of rod; A is controlled operation angle. EFFECT: expanded operational capabilities. 2 dwg
