Ecological Systems and Devices Annotation << Back DETERMINATION OF NATURAL GAS IN ATMOSPHERIC AIR AND TECHNOLOGICAL GASES Eshkobilov Sh.A., Eshkobilova М.E., Abdurakhmanov E.A. In this article the high-sensitive and selective sensor control is developed, which allows selectively determining of natural gas from a mixture of combustible substances. The developed sensor system is applied to measurement pre-explosive concentration of natural gas in atmospheric air in explosive zones, industrial premises of pump stations, petroleum bases, gas stations, objects of the oil-extracting and gas processing enterprises; objects of gas facilities, premises of boiler-houses and all other objects, where the constant control of concentration collecting of natural gas is necessary. The sensor includes the stationary electrical device with convection by submission of controllable environment. At excess of concentration of natural gas, the sensor control begins to signal about it (as sound and light). Keywords: natural gas; concentration; atmospheric air; sensor control; gas actuator; voltage of a feed; graduating characteristics; carbon monoxide; hydrogen.
