It is applicable to the gas safety monitoring of the oilfield well site (driller's room, metering room, duty room, wellhead, pump area, tank area, generator room, etc.), and detects the concentration of hydrogen sulfide (HS), combustible gas (LEL), carbon monoxide (CO) and oxygen (O ²) in the environment in real time....
Main functions：
1. Real-time monitoring: the LCD screen of the main control box displays the gas concentration and unit of each measuring point in real time;
2. Two-level alarm: support independent setting of level 1 (early warning) and level 2 (high alarm), and the alarm value is adjustable;
3. Acousto-optic linkage: alarm signal linkage, three-color or monochrome acousto-optic alarm, graded drive, no dead angle coverage on site;
4. Fault self-check: automatically identify and prompt the faults such as sensor disconnection and short circuit;
5. Data record: alarm events and fault events are automatically stored, and historical records can be queried;6. Signal remote transmission: support 4-20mA/Modbus RTU/Modbus TCP is uploaded to SCADA or central control room at well site.
