　　IICJY4/25 methane oxygen analyzerworking principle:

　　1. Oxygen detection: The measuring device uses electrochemical components as the conversion element for oxygen electrical signals. The electrical signal is processed by an AD converter and a microcontroller to drive a digital tube to display the corresponding value. When the oxygen content value is below the alarm point, the measuring device will emit flashing and buzzing signals.

　　2. Methane detection: The conversion of methane electrical signals in the detector is achieved by a Wheatstone bridge composed of carrier catalytic elements. The bridge detection arm consists of black and white elements, and the bridge auxiliary arm consists of a metal film resistor and a potentiometer. When gas containing methane enters the gas chamber, the bridge outputs a signal V proportional to the concentration of methane gas. After compensation, it enters the AD converter and is processed by the microcontroller to drive the digital tube to display the corresponding value. When the methane concentration value exceeds the alarm point, the instrument will emit flashing and buzzing signals.

　　Mining methane oxygen detectorWhen the power supply voltage is lower than 3.2V, the undervoltage shutdown circuit will activate, issue an undervoltage shutdown command, and turn off the power supply.

　　IIICJY4/25 methane oxygen analyzerThe whole machine circuit consists of power supply, methane detection, oxygen detection, preamplifier, microcontroller circuit, digital display, sound and light alarm, etc.
