Abstract
Изобретение относитс к приборостроению и может быть использовано при контроле изменени давлени воздуха в пневмосистемах или масла в системах смазки двигателей внутреннего сгорани . Цель изобретени - повышение надежности работы и технологичности изготовлени . В сигнализаторе внутри диэлектрического колпачка 3, снабженного сферической поверхностью 12, размещен подвижный контакт 10. На выступающем над поверхностью контакта 10 конце толкател 9, выполненного из неэлектропроводного материала, насажена токопровод ща пружина, свернута в тороидальное кольцо 11. Повышение давлени на мембрану 4 вызывает перемещение толкател 9, которое приводит к раст жению кольца 11 и прекращению электрического контактировани с выводной клеммой 13. В исходном состо нии цепь сигнализации замкнута за счет контактировани кольца 11 с клеммой 13, а через подвижный контакт 10 с неподвижным контактом 8. 2 ил.The invention relates to instrumentation and can be used to control the change in air pressure in pneumatic systems or oil in the lubrication systems of internal combustion engines. The purpose of the invention is to increase the reliability of work and manufacturability. A movable contact 10 is placed in the detector inside the dielectric cap 3 provided with a spherical surface 12. A conductive spring is seated on a protruding end of the contact 10 at the end of a pusher 9 made of non-conductive material pusher 9, which causes the ring 11 to stretch and the electrical contact with the output terminal 13 is discontinued. In the initial state, the signaling circuit is closed by contact ring 11 audio terminal 13, and through the movable contact 10 with the fixed contact 8. 2 yl.
