- Oxygen (O₂) monitoring
- Additional gas sensors available on request
The detector is ATEX and IECEx certified, rated IP66, and suited for both indoor and outdoor use.
Seamless integration with plant control systems
RAEGuard Lite supports industry-standard output options to ensure compatibility with your site’s infrastructure:
- 4–20 mA analog output (source type)
- RS485 Modbus RTU for remote monitoring
- Optional HART® 7.2 protocol for advanced diagnostics and configuration
These options allow the RAEGuard Lite to connect easily to SCADA, DCS, or PLC systems, making it a flexible part of your gas detection network.
Simple installation and contactless maintenance
Designed to reduce install and service time, RAEGuard Lite features:
- Modular terminals and pluggable PCBs for easy wiring
- Magnetic wand interface for contactless, non-intrusive operation
- U-bolt mounting for walls or pipes
- LCD display with bar graph and icon-based feedback
- Three LED status indicators (fault, alarm, normal)
It also includes reminders for sensor calibration and lifecycle management, ensuring compliance and reducing maintenance gaps.
