Functional Features Amplify weak raw flame signal from UV or IR flame probes. Signal filtering circuit rejects false flame signal caused by sunlight, hot refractory surface and electrical arc. Adjustable flame sensitivity threshold for different combustion fuels. Relay contact output for flame on / flame off status to burner management system. 4-20mA analog output provides flame intensity value. Self-test circuit verifies amplifier hardware health automatically. Front panel indicator shows flame presence and fault state.
Application Scenarios Industrial boiler burner flame monitoring, gas turbine flame detection, furnace combustion safety supervision, refinery heater flame protection, power plant burner management system.
Performance Parameters Fast response to actual flame loss event. High discrimination capability to suppress false flame signals. Adjustable sensitivity adapts to natural gas, fuel oil and other fuels. Stable signal processing under industrial power fluctuation. Long continuous operating life for combustion safety system.
Material Composition Enclosure: metal steel cabinet housing. PCB: FR4 multilayer printed circuit board. Core components: signal amplifier chip, filter circuit, comparator, sealed safety relay. Terminal block: screw type wiring terminal. Indicator: LED status lamp.
Structural Features Wall mounted metal enclosure, internal PCB fixed to base plate. Circuit layout divides flame signal input circuit, signal processing circuit and power output circuit. Front cover with viewing window for status LED observation. Screw terminal blocks arranged separately for sensor input, power supply and output wiring.
Working Principle UV or IR flame probe captures flame radiation signal and sends weak raw signal to amplifier input terminal. The amplifier circuit amplifies and filters the signal, eliminates interference signal from hot surfaces or ambient light. The signal processor compares processed flame intensity with preset threshold. If flame intensity exceeds threshold, relay closes to indicate flame present. If flame intensity drops below threshold for preset time, relay opens and triggers flame loss alarm. 4-20mA analog signal outputs real-time flame intensity value to DCS or burner controller. Hardware self-test runs periodically to detect internal circuit fault.
Installation Requirements Mount metal enclosure firmly on solid wall near burner control cabinet. Use shielded cable for flame probe wiring, separate from ignition high voltage cable. Select proper AC power supply by internal jumper setting before power on. Set flame sensitivity threshold according to burner fuel type and operating condition. Check wiring and test flame on and flame off function after installation.
Usage Notes Flame probe cable cannot run together with ignition high voltage cable, which causes false flame signal. Adjust sensitivity strictly according to site combustion condition, avoid false flame or missing flame detection. Cut off power before opening enclosure cover. Inspect wiring terminals regularly for looseness. Test flame detection function during boiler periodic maintenance.
