GAS ANALYSER Russian patent published in 2023 - IPC G01N21/3504 

FIELD: measuring technology.

SUBSTANCE: invention relates to devices designed to determine the concentration and transmit information about the content of flammable gases and vapours of flammable liquids, toxic gases and oxygen in the air, as well as giving a warning signal about the corresponding levels. The gas analyser includes a housing with a measuring chamber attached to it, made with the possibility of inlet and outlet of the analysed medium, in which a sensitive element is placed for measuring the parameters of the analysed medium, and on the surface of the housing there is a cable entry for connecting external circuits and a connector for a contact connection unit, and the main electronic unit with a microprocessor, a digital-to-analogue converter unit, an interface unit are located inside the housing. Additionally, the gas analyser contains a radio communication unit installed inside the housing to provide remote access to the gas analyser and an indication unit for displaying operating information outside the housing, wherein the interface unit connects the digital-to-analogue converter unit, the radio communication unit, the sensing element and the display unit with the main electronic unit, and the digital-to-analogue converter unit is configured to form a unified analogue signal, and its output is connected to the contact connection unit.

EFFECT: improving the functional and operational qualities of the gas analyser.
