LUMIGLAS® ALUMINUM MINI-EX LIGHT SERIES USL 05-EX
The Lumiglas® Aluminum Mini-EX Light Series USL 05-EX is small but effective. Download the datasheet for more on explosion proof lighting for sight ports.
Overview
Small in size and rated EEx d IIC T3…T6 for all explosion classes, the USL05-Ex Luminaire is as versatile as you could ever want. It can be configured for integral light/sight glasses in its single-port version, or for separate light and sight glasses in a dual-port version. Depending on the size sight glass, it can be used with circular sight glass fitting weld-on styles Series DIN28120 , ANSI flange bolt-on types , and with visual flow indicators.
The USL05-Ex lights are Cenelec approved for Class IIc for Zones 1 & 2 (all explosion classes) and are dust and waterjet proof to IP 65, EN 60598 and NEMA type 4. It can be used in virtually any hazardous area and is suitable for food processing. Housing measures only 5.5-in. long by 2.75 in. diameter. Supply voltage can be 12 VDC, 24 VDC, 120 VAC or 230 VAC.

For mounting on sight glass fittings:
This compact Explosion Proof sight glass luminaire is designed for universal applications in potentially explosive environments. It is ideal for use in combined sight and light-glass arrangements, either as a single flange version or with two separate flanged ports.
Compact yet powerful:
Glare-free illumination; for use with circular weld-type sight glass fittings to DIN 28120 or similar, Flange Bolt-Ons, weld-neck type sight glass fittings MV to DIN 11851, Sanitary Clamp Connections and Visual Flow Indicators.
Optimal design of threaded front lens ensures maximum light efficiency
Application: For illuminating the interior of tanks, hoppers, silos, agitators and other - normally closed - vessels and reactors as well as visual flow indicators in potentially explosive environments. Gas: Zones 1 and 2, Dust: Zones 21 and 22 Suitable for use in food processing industries.
Protection: IP 65 and IP 67 to DIN EN 60529
Operating conditions:
Independent of the internal pressure/vacuum in vessel. Under no circumstances should a sight glass luminaire be used to close a vessel port or replace the cover flange or the sight glass/ luminaire assembly.
Lumiglas luminaires of this series are approved for use in ambient temperatures of up to 60°C, depending on the lamp bulb fitted.
