Function and Working Principle
The device operates using an open-path infrared sensing principle, where a transmitter emits an infrared beam toward a corresponding receiver.
It is responsible for:
- Monitoring gas concentration across an open detection path
- Detecting combustible gas clouds in real time
- Triggering alarms when gas levels exceed safety thresholds
- Providing early warning for industrial safety systems
- Supporting integration with emergency shutdown systems
System Role in Architecture
The transmitter is part of a fixed industrial gas detection safety system.
It is typically used for:
- Refinery perimeter monitoring
- Pipeline corridor protection
- Offshore platform safety zones
- LNG facility gas detection systems
- Large chemical plant hazard monitoring areas
It functions as a front-end field safety device feeding data into central control and safety systems.
