Flame detector probes (sensors) are the core components of flame detection systems. They rapidly detect flame signals in the early stage of a fire by identifying ultraviolet (UV), infrared (IR), or specific spectral characteristics​ generated by flames. Various probe forms (e.g., detector heads with indicator lights, junction box - type sensors, explosion - proof probes, etc.). These probes are suitable for different scenarios (industrial plants, warehouses, gas stations, etc.) and can trigger alarms at the onset of a fire, buying crucial time for personnel evacuation and fire suppression.
