Abstract

The design of a nondispersive optical infrared gas sensor with two infrared sources and a single sensor is presented. The operation of the device with the time separation of active and reference signals is demonstrated. An additional broadband photodetector is used to control the aging of radiation sources. The sensor is designed to determine the concentration of methane in an air–gas mixture with a methane volume fraction of 2.2% at most. The proposed sensor design makes it possible to determine the concentration with an accuracy of ±0.1% of the volume fraction of methane in the temperature range from –20°C to +50°C at a temperature change rate of no more than 2°C/min.
