The AT-EG01 Explosion-Proof Fixed Gas Detector is designed for fixed installation in industrial gas monitoring applications. It is suitable for hazardous and non-hazardous areas within Class II explosion-proof environments, according to the product manual.
Depending on the target gas, the detector is equipped with a corresponding sensor module to monitor the concentration of specific gases in the surrounding atmosphere. The target gas, detection range and alarm setpoints are specified on the product nameplate and should be confirmed according to the project requirement before ordering.
The detector provides real-time gas concentration display with current alarm status indication. It supports 4-20mA standard analog output, RS485 digital communication with Modbus RTU protocol, and passive relay contact output for alarm or equipment linkage.
With die-cast aluminum housing, Ex d IIC T6 explosion-proof rating, IP66 ingress protection and DC24V industrial power supply, AT-EG01 is suitable for industrial gas leakage monitoring, gas alarm systems, control panel integration and hazardous area applications.

Maximum contact capacity: 250VAC, 2A
Low alarm and high alarm output modes are available
Relay output mode can be configured as standard or pulse mode
Standard Mode:
Relay closes upon alarm and remains closed.
Pulse Mode:
Relay closes upon alarm and opens after 3 seconds.
The relay output can be used for alarm linkage according to project design, such as connection to gas alarm control panels, ventilation fans, solenoid valves, sounder beacons or PLC input modules. External load design should follow the project electrical control requirements.
The detector must be installed where gas leakage is likely to occur. The optimal mounting position should be selected according to the density of the target gas relative to air.
For gases denser than air:
Install the detector near the potential leakage source, at a height of 0.3 to 0.6 meters above the ground or floor level. The sensor element must face downward.
For gases lighter than air:
Install the detector near the potential leakage source, at a height of 0.5 to 2 meters above the leakage source. The sensor element should face downward.
General installation requirements:
Choose a location free from impact, vibration and strong electromagnetic interference.
Ensure easy access for maintenance, inspection and calibration.
Keep a minimum clearance of 0.5 m from surrounding pipes and equipment.
Route the cable through the cable gland.
A sealing operation with 2 cm of epoxy resin potting compound is required at the wiring port.
Do not open the cover when energized.
Use proper grounding. The detector is equipped with internal and external grounding bolts.
AT-EG01 is suitable for fixed industrial gas leakage monitoring applications where continuous gas concentration measurement, alarm output and system integration are required.
Typical application areas include:
Industrial gas monitoring systems
Hazardous industrial areas
Gas storage areas
Gas pipeline areas
Valve stations
Boiler rooms
Generator rooms
Chemical plants
Industrial refrigeration areas
Cold storage technical areas
Factory gas safety systems
Gas alarm control panel systems
PLC or industrial monitoring system integration
The exact gas type and application should be confirmed before ordering because the target gas, detection range and alarm setpoints are configured according to the product nameplate.
