The technical scheme is widely applicable inevitably.
Description
Technical field: [0001] The invention is mainly applied to the online continuous monitoring of the liquid level. Background technique: [0002] There are many devices currently used for continuous on-line monitoring of liquid level, and the main applications are magnetic flip type and micro pressure input type. The magnetic flip-type liquid level monitoring device is easy to jam and has low resolution; the micro-pressure input liquid level monitoring device has poor resistance to space electromagnetic interference and large temperature drift, which often causes false alarms of liquid level exceeding the limit, which brings serious problems to related equipment. hazards to safe operation. Invention content: [0003] The purpose of this invention is to fundamentally solve the technical defects of the existing technology and patented technology in monitoring the liquid level, and propose a new technical solution, which is characterized in that the thin steel wire ropes are r...
