Abstract

Development of the new light sources for middle infrared region opened new perspectives for methane detection. Possibilities of non-dispersive infra-red open path methane detector operating at 2.3 μm wavelength are discussed. Analytical model of NDIR methane sensor is considered and detector calibration curve for LEDs is presented. The effects of the influence of the methane concentration and the atmospheric precipitations on detector sensitivity are discussed.
