INNER PRESSURE MONITORING DEVICE FOR HIGH PRESSURE GAS CYLINDER

摘要

PROBLEM TO BE SOLVED: To surely monitor the inner abnormal pressure of many high pressure gas cylinders and conduct the monitoring with ease and low cost by simple equipment. SOLUTION: Each high pressure gas cylinder B... is provided with detectors 2... which detect the inner pressure being under a specified value, and indicators 3... which become a display mode by the detection of the detector 2. And all high pressure gas cylinders B are divided into a plurality of groups G1a..., indictors 4a... that become the display mode by the detection of the detector 2 any one of the group are provided in each group G1a..., then lower order groups G1a... are further divided into upper order groups 2a..., indictors 5a... that become the display mode by the detection of the detector 2 of any one of the upper order group are provided in each upper order group G2a.... A display block A2a constitutes them and the indictors 5a... are built like Pyramid in turn and the indicators 5a... of the final display block A2a is provided in the monitoring S.
