Fire flame detector explosion-proof "SPARK" IP 330/3-20 IR (infrared) range is a development of a well-proven line of flame detectors IP 330/3-20. In this model, design changes were made, which allowed to reduce production costs, while increasing the share of the Russian component, while maintaining all the technical characteristics of the fire detector IP 330/3-20.
Fire flame detector "SPARK" IP 330/3-20 consists of a three-frequency IR sensor and microprocessor control controller, housed in a single explosion-proof housing.
The wavelengths emitted by heated objects depend on the heating temperature: the higher the temperature, the shorter the wavelength and the higher the intensity of radiation. In this regard, analysing the signal in 3 wavelength ranges allows to exclude false alarms from IR interference sources.
