METHOD OF MEASURING TEMPERATURE, MOISTURE CONTENT AND RATE OF CHANGE THEREOF IN SEALED CONTAINER WITH GASEOUS MEDIUM AND DEVICE THEREFOR Russian patent published in 2016 - IPC G01N27/416 

FIELD: measurement technology.

SUBSTANCE: invention can be used in methods for analysis of gaseous media and devices for measuring parameters of gaseous media, for control and determination of physical and chemical parameters of said media. Method of measuring temperature, moisture content and rate of change thereof in sealed container with gaseous medium involves installation in container of analysed objects with time-variable physical and chemical parameters and temperature and humidity sensors, dynamic measurement of parameters of gas medium using said temperature and humidity sensors, conversion of measured analogue signals of sensors into final data type. Before measurement of parameters of gas medium, method includes installing in each difficult to access area of container with analysed objects as measuring instruments combined temperature and humidity sensors and subsequent sealing of compact container with analysed objects and measuring instruments, which is then further placed in protective dismountable container, space of which is filled with additional measuring instruments, and protective container is placed in a restricted climatic zone with specified temperature and humidity conditions. Then, measuring instruments are turned on and dynamic measurement of gas medium is performed both in sealed container with analysed objects, and in protective container, from which measured signals are transmitted to corresponding sockets of an independent measurement-conversion unit (AIPB), and converted signals are transmitted to a PC, where they are compared with critical values. Unlike existing device for measuring temperature and moisture content and rate of change thereof in a sealed container with gaseous medium with analysed objects placed therein, characterised by time-variable physical and chemical parameters, and equipped with measuring instruments, according to invention a sealed container with analysed objects is placed in protective container with measuring instruments, installed in a climatic zone with specified temperature and humidity conditions, each of measuring instruments is equipped with individual switching elements, wherein all switching elements, conducting measured signals from measuring equipment, are assembled into a single line of switching elements and are connected to common connectors (sealed adapters) installed in series in a sealed container with analysed objects and in a protective container, and are connected to corresponding connectors of independent measurement-conversion unit (AIPB).

EFFECT: technical result is possibility of insulation against external factors, providing dynamic control of time-varying gas medium of sealed containers with analysed objects, in which there are difficult to access zones for installing measuring equipment, minimising operational process and reduction of labour resources of operators, optimising measurement and control process.
