Title
(EN) ULTRAVIOLET FLAME DETECTOR
(FR) DÉTECTEUR DE FLAMME AUX ULTRAVIOLETS
Abstract
(EN)
A flame detector that includes a spacer, a UV transparent window, and a UV sensing elements. The spacer has a spacer wall that extends along a first axis between a first spacer end and a second spacer end. The UV transparent window is disposed at the first spacer end. The spacer wall and the UV transparent window define a gas space. The UV sensing elements is disposed within the gas space.

L'invention concerne un détecteur de flamme qui comprend un élément d'espacement, une fenêtre transparente aux UV et un élément de détection d'UV. L'élément d'espacement a une paroi d'élément d'espacement qui s'étend le long d'un premier axe entre une première extrémité d'élément d'espacement et une seconde extrémité d'élément d'espacement. La fenêtre transparente aux UV est disposée au niveau de la première extrémité d'élément d'espacement. La paroi d'élément d'espacement et la fenêtre transparente aux UV définissent un espace de gaz. Les éléments de détection d'UV sont disposés à l'intérieur de l'espace de gaz.
