The Papenmeier Lumistar luminaires USL 13-LED and USL 33-LED are designed for universal applications, suitable for mounting on sight glass fittings.
The USL 13-LED features a hinged bracket for versatile installation, while the USL 33-LED is a special variant for sterile environments with an adapter collar for fitting over flanges.
These luminaires are ideal for combined sight and light ports (single-flange version) or for two separate ports (two-flange version). They provide glare-free illumination and are compatible with circular sight glass fittings similar to DIN 28120/DIN 28121, screw-type sight glass fittings similar to DIN 11851, as well as METAGLAS and BioControl fittings.
Applications
They are suitable for use in chemical, pharmaceutical, biogas, and food processing industries. Typical uses include illuminating bioreactors, laboratory mixers, filters, tanks, agitators, separators, pipelines, and other normally closed vessels in non-explosive environments.
Protection Class
The luminaires have an IP65 rating according to EN 60529 / DIN VDE 0470 Part 1, making them dust- and waterjet-proof.
Operating Conditions
The luminaires operate independently of internal pressure or vacuum in the vessel but should never be used alone to close a vessel port or replace the mating flange or complete sight glass flange assembly. The maximum admissible ambient temperature at the cable entry gland is 40°C.
