Optical aperture
For the compact flame controllers CFC 200 IR and CFC
200 IR3 radiation to the sensor element (3) can be re-
duced with an optical aperture. When the smallest hole is
positioned in front of the sensor element, the lowest inci-
dence of radiation is done on the element. The diaphragm
can be locked in four different positions.
The diaphragm is mechanically coupled to the detector
holder. To adjust the diaphragm unfasten screws through
the holes in the shield of the preamplifier. The top screw
(1) sets the aperture, the lower screw (2) centeres aper-
ture.
