Pressure Compensation Method for Mine-used Infrared Methane Sensor

More Information
  • Published Date: July 19, 2014
    Graphical Abstract
    • Abstract
  • The accuracy, by using infrared ray to detect methane content of coal mine gas, is affected by pressure in coal mine environment. In this article, a pressure compensation mathematic model is proposed. Taking methane as an example, in order to enhance detection accuracy, the acquisition, analysis and calculation of pressure data are carried out by combination of atmospheric pressure sensor and MCU on hardware circuit level.
