The capabilities of MetaClamp and MetaGlas sight-glass windows have been expanded with the addition of light-emitting diode (LED) lighting technology. Designed for sanitary or hygienic applications in the pharmaceutical, food, beverage, brewery and biotechnology industries, the new MetaClamp LED Ring Light Series SGL (photo) provides both illumination and viewing through the same window. This combination sight and light glass incorporates the MetaClamp system with MetaGlas safety windows. They can be used to view the interior of either new or existing sanitary-processing equipment, such as bioreactors, mixers, brew kettles, filters, tanks, hoppers, silos, agitators, separators, pipelines and other usually closed containers in non-hazardous areas. Unlike other devices that use separate viewing and fiber-optic light assemblies, the MetaClamp LED Light Ring mounts directly onto sanitary ferrules for use in combined sight and light ports (single port). The design is both less expensive and more durable for industrial settings, since it uses fewer sub-assembly components. The unit is approved for ambient temperatures ranging from 0 to 50°C at the cable entry gland. — L.J. Star Inc., Twinsburg, Ohio
