Sight Glass available in six standard sizes that provide viewing areas ranging in size from approximately 3? to 9? in diameter. The weld-on assembly is designed to provide direct visual inspection of process vessels, separators, silos, pipelines and storage tanks. To illuminate the interior of the vessel, an optional LumiStar Light allows viewing and lighting through the sight glass port, saving the additional expense of a separate light port. Explosion proof lights, see USL05-Ex, and non-explosion proof lights, see USL13, are available as well.
These weld-type sight glass fittings, complete with glass disc, seal gasket, and cushion gasket bolted between circular flanges, is the low-pressure version of the DIN 28120. The units can be combined with Lumiglas luminaires, such as the USL05-Ex, USL06-Ex, USL07-Ex or USL08-Ex , for use in hazardous areas. Under all normal working conditions, light options include USL01 , USL13 , USL15 , USL05 , USL06 , or USL07 . For an integral light/sight glass, combine the low pressure unit and LumiStar light. Options include sight glass wipers type SW I .
