Flameproof and intrinsically methane product introduction
Methane breaker is mainly suitable for underground coal mines and other gases(methane, coal dust mixture) occasions, and can be used in underground mining equipment and other large and medium-sized electrical and mechanical equipment,continuous detection of air in the gas concentration near the equipment, when thegas concentration reaches 1.00%CH4 or more, the off immediately sends out sound and light alarm signals, when the gas concentration reaches 1.50%CH4 or more, the off immediate power (cut controlled electrical equipment), to ensure safety in production. When the gas concentration dropped to less than 0.50%CH4,automatically unlock power instrument (recovery controlled electrical equipment), andcontinued to be detected.
Methane power instrument adopts high performance thermal catalytic element, the large scale integrated circuit and new electronic components, digital display, stable performance, the threshold is accurate, rapid response, high precision. Power meterhas the advantages of small volume, low power consumption, simple application,convenient maintenance.
