FIELD: instrumentation.
SUBSTANCE: group of inventions relates to devices for flame detection by means of detectors. The invention proposes a device for flame detection by means of detectors that record different wave length ranges by means of prefilters. The above device includes data processing devices for analysis of signals of detectors, which are connected after the detectors. At least two identical detectors are installed near each other. Each detector is provided with an identical signal processing system, as well as a symmetrical and similar layout. Identical signal processing is performed by means of amplifiers and/or analogue-to-digital converters. Besides, the device has a possibility of simultaneous and synchronous recording of signals to provide an analysis of the received emission by means of an algorithm and irrespective of interference, namely by means of the analysis of the signal ratio.
EFFECT: creation of flame detection devices providing an accurate result of detection and reduction of response time for flame detection.
