Product Description
GAC-M10 Multi-Point Gas Detection System
One sensor with sixty-four sampling points - ideal when coverage matters more than continuous per-point measurement.
System Overview
The GAC-M10 provides cost-effective gas monitoring by trading continuous per-point measurement for comprehensive coverage. One sensor services up to 64 points, completing a full cycle within 30 minutes with sampling distances up to 400 meters.
How It Works
The system consists of a detection cabinet and control box. Using a PLC control unit, centralized sampling pumps and switching valves sequentially draw gas samples from multiple monitoring points and send them to the same sensor for analysis. The system performs cyclic detection of gas concentration at each point, with measurement and alarm capabilities.
Selection Guidance
- Choose GAC-M10 for low-risk dispersed monitoring points
- Choose GAC-M20 where every point requires continuous dedicated measurement
- Complete cycle time: full round of all points within 30 minutes
- Maximum individual sampling run: 400 meters
- Environmental rating: IP55, carbon steel, -10°C to 55°C
Pipeline Layout Requirements
- No single sampling run exceeds 400 meters
- Maximum 64 points total (62 external monitoring, 1 internal, 1 external reference air)
- Protect lines against mechanical damage and condensation
- Separate from high-temperature surfaces
- Label both ends of every run to prevent identification errors
- Cabinet footprint: 800 * 200 * 500 mm, up to 250 kg
- Power supply: AC 220V ±15%, 50-60 Hz
