MULTI-COMPONENT GASEOUS MEDIUM IN THE AIRTIGHT CONTAINER STATE PARAMETERS CONTROL METHOD Russian patent published in 2018 - IPC G01N27/416 

FIELD: measuring equipment.

SUBSTANCE: invention relates to the field of the changing over time gas medium state parameters measuring methods and can be used to monitor the containing toxic or explosive-fire hazardous components observable multicomponent gaseous medium safe state. Proposed is the multicomponent gaseous medium parameters measuring method in the airtight container with the objects stored therein. Method comprises the parameters measuring using temperature, relative humidity and pressure sensors, and the multicomponent gaseous medium safe state monitoring. According to the invention, sealed container with multi-component gaseous medium with the objects stored therein is placed in the protective container, which is then placed in the climatic chamber. In each of the mentioned containers and in the climatic chamber, installing the system of independent small-sized temperature, relative humidity and pressure sensors or sensors with these parameters combined function. Monitoring of the multicomponent gaseous medium changing parameters is carried out in real time with the measuring signals recording and the measured analog signals subsequent transmission to the analog signals into digital signals conversion stage and transmission of the latter to the PC, in which the observed multicomponent gas medium parameters current values DB is generated in automatic mode, and in which there are preformed nominal values DBs and the critical values DBs of the multicomponent gaseous medium measured parameters. Multicomponent gaseous medium in the sealed container current safe state control is performed based on the comparison of differential pressure values, relative humidity and temperature in the sealed container multicomponent gas environment with objects stored therein and protective container in comparison with the gaseous medium in the climate chamber parameters and in comparison with these parameters critical values in the control DBs. AT that, if the measured parameters current values are in the range of values of the parameters nominal values DBs and do not reach the parameters critical values DBs values, ascertaining the multicomponent gaseous medium in the airtight container safe state presence.

EFFECT: increase in the measured results reliability.
