The ADI 7200 SE system measures stray emission both with and without deflection at CRT production line speeds.
Stray emissions occur when electrons generated by debris inside a cathode ray tube (CRT) are discharged, striking the phosphor on the screen of the CRT and creating an undesirable illumination or glow effect.
The Stray Emission system detects contaminants inside picture tubes which cause "afterglow" when the TV is shut off.
Improvements specific to the Joliet refinery include reducing nitrogen oxide emissions by 1,818 tons per year and sulfur dioxide emissions by 24,069 tons per year; implementing an extensive wastewater monitoring and record-keeping system; and taking measures to minimize or eliminate benzene emissions and stray emissions of volatile organic compounds and hazardous air pollutants.
Kleerdex explains that newer MRI instruments produce stronger magnetic fields to produce clearer images more rapidly; however, these fields also intensify stray emissions generated by the polymer used in the housings.
This increased intensity created its own challenge when it was found that stray emissions from the plastic housings also increased in intensity.
The ADI 7200 SE is a vision-based inspection system, which detects and evaluates the amount of stray emissions from television tubes.
Fugitive emissions are defined as hard-to-detect stray emissions emanating from pipes, valves and flanges.
