AT-EG01 Hydrogen Gas Detector is designed for fixed hydrogen gas monitoring applications. According to the product manual, the detector is configured with the corresponding sensor module based on the target gas. The target gas, detection range and alarm setpoints are specified on the product nameplate.
The detector provides real-time concentration display and alarm status indication. It supports 4-20mA analog signal output, RS485 digital communication using Modbus RTU protocol and passive relay contact output for alarm or control system integration.
With die-cast aluminum housing, Ex d IIC T6 explosion-proof rating, IP66 ingress protection and DC24V industrial power supply, AT-EG01 Hydrogen Gas Detector is suitable for fixed industrial hydrogen leakage monitoring and hazardous area gas detection applications.

Low alarm and high alarm output modes are available.
The detector must be installed where gas leakage is likely to occur.
For gases lighter than air, the detector should be installed 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 notes:
Avoid strong impact and vibration.
Avoid strong electromagnetic interference.
Ensure easy access for maintenance and calibration.
Keep a minimum 0.5 m clearance 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.
