PRESSURE DIFFERENCE INDICATOR

摘要

FIELD: measurement equipment.SUBSTANCE: in a vessel of a pressure difference indicator there are insulated holes. In one of holes there is a spring-loaded magnetically operated sealed switch. In another hole there is a movable system with a permanent magnet. Specified holes are arranged in parallel. The movable system comprises a fixed bushing with a spring-loaded piston and a guide. The permanent magnet is fixed in the piston body perpendicularly to its axis in the plane stretching via the axis of the magnetically operated sealed switch and is spring-loaded.EFFECT: simplified tuning of a pressure difference indicator providing for efficient usage of a filter.2 cl, 2 dwg
