Design of a Methane Concentration Detector Based on Spectrum Absorption
2013
Proceedings of the 2nd International Symposium on Computer, Communication, Control and Automation
unpublished
It is necessary to have a methane concentration detector in the coal mine workspace. In this paper, a methane detector is designed which is based on non-dispersive infrared spectrum absorption theory and employs the single-light beam and double wavelength differential detection technology and integrative infrared filter detector. Performance test for this system has been conducted, and the experimental data has been fitted and relation formula between methane concentration and voltage under
