Abstract
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.
Claims19
A flame detector, comprising:
- a spacer having a spacer wall extending along a first axis between a first spacer end and a second spacer end;
- a UV transparent window disposed at the first spacer end;
- the spacer wall and the UV transparent window defining a gas space;
- and
- UV sensing elements disposed within the gas space;
- the spacer wall defining a recess that extends from the first spacer end towards the second spacer end;
- wherein the UV sensing elements include:
- an anode disposed within the gas space and extending into a first gap defined by the spacer wall;
- a cathode disposed within the gas space and spaced apart from the anode, the cathode extends into a second gap defined by the spacer wall;
- and
- a gas mixture within the gas space, the gas mixture being arranged to enable a gas electron multiplier effect.
