Luminaires (Non-Ex)

Also available in LED technology

Fully Sealed Lumistar Sight Glass Luminaire with cover glass compact, all stainless steel

• USL 16: for general applications, mounted with hinged bracket
• USL 36: special variant for sterile environments with adapter collar
  for fitting over flanges, etc.

The perfect combination of flush contours and smooth surface:

This sight glass luminaire is designed for universal applications. It is ideal for use in combined sight and light ports (single-flange version) or for two separate ports (2-flange version).

Ultra-bright LED provides 3000 lumens

Compact design, powerful light output:

Glare-free illumination; suitable for circular sight glass fittings to DIN 28120/DIN 28121 or similar, for screw-type sight glass fittings in compliance with DIN 11851, and for METAGLAS® and BioControl fittings.

Application in chemical, pharmaceutical, biogas and food processing  industries:

It is ideal for illuminating bioreactors, laboratory mixers and filters as well as the interiors of tanks, agitators, separators, pipelines and other, usually closed, vessels in non-explosive operating environments.

Protection class: Dust- and waterjet proof, IP 65 according to EN 60 529 / DIN VDE 0470, Part 1

Max. admissible ambient temperature at the cable entry gland with halogen version: 90°C; with LED version: 40°C.

This LIGHT is the world’s brightest sight glass luminaire:  LED luminaire is four times brighter than a typical sight glass light, offering an unprecedented view of processes.  Ultra-bright LED provides 3000 lumens at full brightness, four times the light output than a typical 100-Watt halogen light.  The total internal reflection (TIR) lens with 23-degree beam angle, is ideal for vessel illumination through a sight glass with maximum light output and less than 5% loss of light output.  The light is capable of continuous operation and emits cool white, 5500K color temperature, optimized for stainless steel vessels.  The light is designed for cool operation equipped with temperature-based current limiting and automatic dimming; over temperature shutdown.  The LEDs have a long service life and are vibration and impact resistant.  No heat radiation is directed into the process vessel (cold light output).   The housing is available with a mounting bracket (USL16 Light) or a sanitary clamp connection (USL36 Light)
