產品介紹
The combustion process, depending on the type of fuel used, emits more or less light radiation belonging to the ultraviolet, visible or infrared spectrum. Of course, gas oil combustion generates a very bright flame, which is easily detectable by means of sensors using common photocells; nevertheless, at the same time gas oil combustion generates a quantity of substances not completely burnt (unburnt substances), which pollute and also dirty the combustion chamber step by step. By suitably adjusting the combustion, it is possible to solve this problem and improve the flame quality, making it similar to the flame produced by gas, natural gas or propane combustion (blue flame).

Since photocells are not sensitive to blue flame light, in most gas burners the presence of flame is detected by exploiting the ionization principle; to this purpose, you simply need an electrode (electrically isolated metal rod) suitably "immersed" in the flame. This principle is not easily applicable in oil burners, as the electrode immersed in the flame gets dirty quickly (consequently losing its efficiency) and modifies the turbulence in the combustion chamber, thus creating serious problems.

For all these reasons, it is necessary to detect the presence of flame by means of ultraviolet sensitive detectors.

The FDx sensor uses a silicon preamplified active element, specifically designed for blue flame burner applications; the UV light peak detection of this sensor is around 310 nm. Thanks to the incorporation of suitable electronic components, this device can be fitted to the BRAHMA control boxes of the EUROBOX, EUROFLAT, MINIFLAT, MICROFLAT and EUROGAS series (suitable for gas burner applications); moreover, this sensor is particularly well fitted for the control boxes type GR1, GR1/Z and GR2 of the EUROOIL series and for any control boxes of the OIL-SYSTEM series (suitable for oil burner applications).

In order to meet the widest range of market requirements, this device is available in the FD1 version (with front view) and in the FD2 version (with lateral view). Please note that the FDx detector is sensitive to the ultraviolet component of visible light; therefore, its use is recommended in burners fitted with closed combustion chambers and in an application environment perfectly shielded from visible light.
