The control system adjusts the operating parameters of the equipment accordingly, such as adjusting the fuel supply of the burner, controlling the power of the cutting equipment, etc., in order to achieve precise control of the industrial production process, improve product quality and production efficiency.

Digital display: Equipped with an intuitive digital display screen, it presents real-time key parameters of the flame, such as flame intensity, combustion stability, etc. Operators do not need complex instrument detection, and can quickly understand the flame status through the display screen, which facilitates equipment debugging, maintenance, and daily monitoring.

Working principle

The DFI-150-0003 Limelight diagnostic board receives signals such as infrared, ultraviolet, ion current, and visible light generated by flames through specific sensors. After being preliminarily amplified by a preamplifier, these signals are transmitted to the signal processing circuit. The signal processing circuit uses complex algorithms to analyze, filter, and extract features from signals, in order to distinguish between real flame signals and environmental interference signals. Once the flame signal is confirmed to be valid, the diagnostic board will generate corresponding control signals and status information based on preset rules and algorithms. On the one hand, this information is transmitted to the external control system through the output interface for device operation control; On the other hand, it is visually presented on a digital display screen, making it convenient for operators to monitor in real-time. At the same time, the self diagnostic module will continuously check the hardware and software operation status of the diagnostic board itself to ensure the reliability of the entire system.
