2.1 Intended use
The illuminators are used in direct water level gauge which can be mounted on steam generators. In the sight opening,
the water space is indicated in green and the steam space in red.
The level gauge works on the principle of communicating pipes. With the LL RGx illuminators, red and green light falls
on the display unit. If there is water in the display area, then the light rays will be diverted in such a way that the green
light beam falls on to the slit diaphragm of the display box. In the steam area the light rays are not diverted and the red
light beam is projected.
