GAS ANALYZER Russian patent published in 2003 - IPC

FIELD: measurement technology, equipment analyzing gas in environment at increased positive and low negative temperatures. SUBSTANCE: gas analyzer has gas sensor, flow choke, gas flow rate booster, information processing unit, analog-to-digital converter, digital indicator of gas content, light system warning of ultimate gas contents, buzzer of ultimate contents, thermoelectric Peltier's module which is directly anchored on structure of gas sensor, temperature-sensitive elements of gas sensor and inlet air flow, two temperature master elements for forced cooling and heating of gas sensor, facility processing information from temperature-sensitive elements and temperature master elements that is connected in series with controller and amplifier controlling direction and strength of electric current passing through thermoelectric Peltier's module and consequently temperature condition of gas sensor. EFFECT: expanded range of working temperatures of gas analyzer, enhanced stability of determination of gas in ambient atmosphere. 1 dwg
