Methane (CH4) detection is critical in the mining industry. The working environment of the mining industry is often underground, which is a confined space that is closed or partially closed, with narrow entrances and exits and poor natural ventilation, easily leading to the accumulation of toxic and harmful, flammable and explosive substances or insufficient oxygen content. If the mine is not properly monitored and ventilated, methane may accumulate to dangerous concentrations. When the methane concentration exceeds a certain limit (usually 5%), it will form an explosive gas mixture after mixing with air, which increases the risk of explosions. Therefore, it is necessary for miners to detect methane levels with a reliable methane detector before entering the mine to ensure a safe working environment.
In the United States, the Mine Safety and Health Administration (MSHA) enforces stringent regulations to ensure mine safety, including the mandatory monitoring of methane levels. MSHA regulations require mine operators to monitor and control methane concentrations to prevent hazardous accumulations.
In this context, it is pivotal to adopt qualified and effective methane detection measures within the mining industry. Cubic, as a leading manufacturer of gas sensors and gas analyzers, has innovatively developed the miniature low power NDIR CH4 sensor, SJH-5B-SL, on the basis of NDIR technology, which is an optimal choice to be integrated into portable methane detectors to realize high accuracy, long lifetime and anti-interference for methane detection in the mining industry.
Based on NDIR technology, Cubic NDIR CH4 sensor SJH-5B-SL can detect 0 to 5% Vol methane (CH4) concentration, meeting the regulatory requirements. It could provide real-time data, enabling rapid response to methane leaks to realize precise and reliable industrial safety alarm. With the low power consumption design, it can be applied for the mining operation scenarios that require optimal energy efficiency, and battery-powered portable or wearable detectors. Specifically, Cubic SJH-5B-SL could enable continuous working current as low as 1mA, and achieve micro ampere level further through flexible intermittent working model. Besides, it continuously maintains excellent performance for superior accuracy over full temperature range and long-term stability based on matrix calibration mechanism and dual beam design. It also features long lifetime of more than 10 years without the need to be replaced frequently, which can reduce maintenance and replacement costs to realize cost-effectiveness.
Due to the advantages of compact size, superior accuracy and low power design, Cubic SJH-5B-SL can be an ideal solution for integration into portable methane detectors in the mining sector.
