The analyzer of methane thermocatalytic fast ATB

Is part of the system Supervisory control and ventilation designed for continuous centralized control teleautomatics the volume fraction of methane and the speed of its rise in the underground workings of mines, develop the layers, dangerous on sudden emissions of coal and gas, issuing commands to the power supply controlled area in excess of maximum permissible volume fraction of methane and the speed of its rise.

Analyzer methane ATB consists of :

apparatus alarm AC-7,

two transducers measuring parameters PPI,

two sensors methane UHF remote,

siren intrinsically safe SI-1,

two line telephone handsets TIT-1.

Products included in the analyzer of methane ATB, have explosion-proof execution with the following types of protection:

Analyzer methane ATB provides:

continuous automatic control of methane volume ratio in the place of installation of sensors;

the issuance signal to shut off electrical power of the controlled part when reaching the maximum allowable volume fraction of methane;

the issuance signal to shut off electrical power of the controlled part when the rate of increase in the volume fraction of methane (0.1 to 0.2) % at 1 s and above;

the issuance signal pre-deactivation of the mechanism plot (combine loading machines and so on) with time delay;

continuous sound and light alarm in accordance with GOST 24032-80;

intermittent sound and light alarm when the RMS-velocity of rise in the volume fraction of methane from (0.1 to 0.2) % at 1 s and above;

remote visual control of methane volume ratio by specifying the device as-7;

the opportunity transfer Manager continuous unified signal about the volume fraction methane;

the opportunity transfer Manager discrete signaling normal operation analyzer, the maximum allowable volume fraction of methane or speed it rise and line break telemetering;

phone the relationship between subscribers and transformers PPI, as-7 and Manager.
