PRESSURE RELAY Russian patent published in 2001 - IPC

FIELD: instrumentation. SUBSTANCE: invention is specifically related to device converting displacement of sensitive elements under action of gas or liquid to electric signals. It can be used in indicators intended for use in systems controlling pressure and draft while automating technological processes. Pressure relay includes sensitive element with rigid center, mobile magnet linked to it, unit of adjustment of hermetically sealed reed relays making it feasible to adjust hermetically sealed reed relays in horizontal and vertical planes with subsequent rigid registration. Contact plates of hermetically sealed reed relays are positioned perpendicular to magnetization axis of permanent magnet, hermetically sealed reed relays are located on adjustment unit at acute angle with regard to direction of movement of magnet. EFFECT: widened operational capabilities of devices controlling pressure and draft of automated technological processes. 1 dwg
