Compact Flame Scanner SAX200

Overview

The Compact Flame Scanner SAX200 is a flame detection device engineered for industrial combustion safety and monitoring applications. It receives optical signals from flame radiation through a combustion chamber window and analyzes them using onboard digital signal processing to extract flame features such as intensity and flicker frequency. When a proper flame is detected, safe fuel flow continues; if not, the scanner triggers safety logic to prevent fuel delivery and reduce explosion risk. 

Designed for robust industrial environments, the SAX200 flame scanner supports standard outputs including RS485 digital communication, 4–20 mA analog output, and dry contact relay, enabling seamless connection to PLC, DCS, or machine safety systems for automatic shutdown, alarm indication, or fuel valve control. 

Key Features & Technology

The SAX200 Compact Flame Scanner incorporates advanced features for flame detection and diagnostics:

• Digital optical flame detection using high-speed 32-bit signal processing to accurately capture flame presence and characteristics. 

• Multi-spectrum flame signal analysis covering UV, visible, and infrared ranges for greater reliability. 

• Standard industrial output interfaces: RS485/Modbus, 4–20 mA, and dry contact relay for direct integration with control and safety systems. 

• Rapid flame loss detection with safety logic interfacing to immediately trigger fuel shut-off or alarm conditions. 

• Designed for continuous operation in challenging industrial environments, with rugged optical sensor assembly and electronic housing. 

The compact style eases installation in tight burner and combustion chamber environments while maintaining high detection accuracy. 

Industrial Applications

The SAX200 flame scanner is used in critical combustion and industrial safety systems, including:

• Industrial burners and boilers where continuous flame monitoring ensures proper combustion. 

• Gas turbines and steam generators requiring rapid flame status feedback. 

• Heat recovery systems and furnaces in petrochemical and refinery environments. 

• Process heaters and industrial combustion appliances for fuel-to-flame verification. 

In these applications, accurate flame scanning helps avoid unsafe fuel flow, prevent thermal damage, and support automated safety shutdown sequences. 

Installation & Integration

Installation involves mounting the compact flame scanner so the optical sensor can view the combustion zone through an appropriate sighting window or optical port. Electrical connections typically include power supply, RS485 communication lines (often Modbus), analog 4–20 mA outputs for control systems, and dry contact relays for alarm or shutdown interfaces. Proper alignment and optical clarity are essential for reliable operation.
