METHANE INDICATOR CMC5
The methane indicator CMC5 is intended to give the light signal at
reaching or exceeding of the two assigned thresholds of methane content in
the environment, as well as for individual illumination of the working
place in the coalmines with gas and dust hazard of any category.
- The methane indicator CMC5 is
integrated with the mining explosion-proof cap lamp.
- The monitoring and warning
about availability of methane in excess of the admissible standards, as
well as the explosion-safety of the indicator are ensured by the special
sensor, electronic devices and design of the casing parts.
