Dimensions and weight of methane detection alarm
Only by tasting sorrow and swallowing bitterness can a fragile mind learn to be strong. As long as you have unchanging dreams, there will be hope ahead. Passing through the years, walking day and night, this road has been bumpy and bumpy, leaving deep and shallow footsteps. Looking back at dusk, this bumpy road is a picture of life. Spring goes and autumn comes, and it will never fade.
A brief description of the mining methane detection alarm product
The methane detection alarm is developed to meet the needs of coal mines in my country for monitoring underground biogas. It can continuously and automatically convert the underground biogas concentration into Standard electrical signals are transmitted to related equipment, and have local display of biogas concentration values, over-limit sound and light alarms and power outage functions. After online inspection by the national explosion-proof inspection agency, it can be connected with various types of domestic monitoring systems and power outage instruments, wind power gas lockout The device is equipped with matching equipment and is suitable for fixed use in coal mining working faces, mechanical and electrical chambers, return air tunnels and other places.
