Technical data
USL 03 LED Sight Glass Luminaire Overview
The USL 03 LED Sight Glass Luminaire is a compact and versatile lighting solution developed for industrial process observation through sight glass fittings and visual flow indicators. Its space-saving design allows installation where conventional luminaires cannot be accommodated, making it particularly suitable for compact process equipment.
Manufactured with a corrosion-resistant stainless steel housing and high-performance LED module, the USL 03 delivers bright, uniform illumination while generating very little heat. The luminaire is ideal for monitoring liquids, mixing operations, filling levels, and product conditions inside closed vessels.
Compatible with circular sight glass fittings similar to DIN 28120, DIN 28121, screw-type fittings similar to DIN 11851, and various flow indicators, it is widely used in food processing, pharmaceutical production, chemical plants, biotechnology, and water treatment systems. Its IP65-rated enclosure and maintenance-free LED technology ensure dependable operation even in demanding industrial environments.
