Description

ДАТЧИК ВЫЛЕТА СТРЕЛЫ ГРУЗОПОДЪЕМНЫХ КРАНОВGAUGE OF DEPARTURE OF THE ARROW OF CRANKS

с возможностью перемещени  в зазоре между двум  парами не св занных общим магнитопроводом сердечников, в которых смонтированы две первичные катушки, включенн.ые в контур генератора синусоидальных колебаний , и две вторичные катушки, соединенные по дифференциальной схеме и подключенные к фазочувствительному детектору, отличающийс  тем, что, с целью упрощени  конструкции и расширени  пределов измерени , экран выполнен в виде винтовой конической поверхностг. закрепленной са полом валу, перемещающемс  поводком по выходному валу, св занному с механизмогл выдвижени  стрелы. 2. Датчик 6 по п. 1, о f л и ч а ю щ и и с   тем, что экран выполнен в виде диска, описанного кривой переменного радиуса.movably in the gap between two pairs of cores not connected by a common magnetic core, in which two primary coils are mounted, connected to a sinusoidal oscillator circuit, and two secondary coils, connected in a differential circuit and connected to a phase-sensitive detector, characterized in In order to simplify the design and extend the measurement limits, the screen is made in the form of a helical conical surface. fixed to the hollow shaft, moving a lead on the output shaft, associated with the mechanism of boom extension. 2. Sensor 6 according to claim 1, about f l and h and y and the fact that the screen is made in the form of a disk described by a variable radius curve.
