USL05 LED – Explosion-Proof LED Luminaire for Hazardous Area Sight Glass Applications

The USL05 LED luminaire provides reliable, high-performance illumination inside tanks, hoppers, silos, agitators, mixers, reactors, and visual flow indicators installed in potentially explosive industrial environments. Certified for Gas Zones 1 & 2 and Dust Zones 21 & 22, this unit is engineered to deliver safe operation in areas where explosive atmospheres are present. It is also suitable for stringent food-processing applications.

Purpose-built for universal installation, the USL05 LED can be fitted into combined sight/light ports using a single flange or mounted via two-port configurations where separate sight and light entries are preferred.
