Description
The IFD20 dual IR-UV flame detector is a kind of new-type intelligent fire detection equipment. This detector is manufactured with the high-performance dual infrared sensing technology and the ultraviolet detection technology, as well as the infrared sensor equipment with different wavelengths and narrow-band filtering and the ultraviolet flame sensing equipment of the solar blind band. Among these three sensors, the infrared sensor and the UV sensor are used to reflect the central wavelength of the flame information in different bands, and the other infrared sensor is used to monitor other infrared radiation in the environment. Combined with the flicker characteristics of the flame, the radiation spectrum with flame characteristics can be identified as a fire alarm by means of the operational analysis with the high-speed microprocessor and technical algorithm. The UV flame sensing equipment is able to suppress the interference from the sunlight in a good manner, so as to achieve a fast response to and accurate identification of the flame signal. In addition, this detector can be used for either dual infrared detection or single ultraviolet detection, and can be also used for both infrared and ultraviolet detection at the same time.
