Air Shield
The air shield (P/N 777650) is suitable for use with the SharpEye 40/40 Series
Optical Flame Detector 40/40U-UB, for both the aluminum and st.st. enclosures.
Optical flame detectors are often used in highly polluted or dirty areas that force
maintenance personnel to access the detector frequently in order to clean its
optical window. The special air shield, developed for SharpEye 40/40 series
optical flame detectors, allows their installation under environmental conditions
where they may be exposed to oil vapors, sand, dust, and other particulate
matter.
The temperature of the air supply to the air shield should not exceed 60°C/140°F
at any time.
