Automatic Analyzer for Methane Monitoring (AAMM) in the pipelines of gas-suction plants (hereafter - Analyzer) is used to monitor automatically methane concentration in pipelines of gas-suction plants, generate sound and light alarm and control signal for switching off the electric facilities when the methane concentration exceeds the permissible level as well as to form and transfer the telemetric information to the surface.
The AAMM Analyzer is produced on the basis of PM-3261.03D Methane Sensor and TX3282.01 Display. The connection diagram of AAMM component parts is shown on the picture.
Measuring range of PM-3261.03D Methane Sensor CH4 volume concentration - from 0 up to 4%; indication range – from 4% up to 100%.
Level of sensor ingress protection – IP65.
Level of sensing element ingress protection– IP54.
Level and type of sensor explosion protection - RÎ (mining extra explosion- proof (Ukrainian standard)) Ia S.
The Analyzer is assembled on the basis of extra explosion - proof mining equipment Ro with the type of spark protection Ia S and with the level of ingress protection not less than IP54.
The Analyzer is designed for application in mines including gas and dust hazardous ones.
