Hinged Light-Sightglass combination ESKS0 pages

Data Sheet 08.02
Lumiglas Light/Sightglass Units Series ESKS or SKS
(hinged sight glass frame with or without luminaire)
• Application:
ESKS integral light/sight glass units have a quick release closure, so that they are a combination of charge/access port and light/sight glass. The integrated lumninaire illuminates the internal of boilers, tanks, bunkers,silos, mixers and other vessels in all non
Ex hazardous areas.
SKS type sight glass ports are of the same design, except they have no luminaire. Both types are suitable for food processing. Usually these units come with a weld flange, but for flat vessel walls they can also be installed with a bolt-on flange.
• Safety precaution:
The unit must never be opened before the pressure inside the
vessel is reduced to zero!
• Protection:
When correctly fitted, dust and waterjet proof to IP 65,
EN 60 529 / DIN VDE 0470 T1
• Ambient condition operating range:
The unit is vacuum proof
and resistant to: 0,5 bar type SKS/ESKS 225 1,0 bar type SKS/ESKS 150
max. vessel temp.: 150°C with soda lime glass
200°C with borosilicate glass
ambient temp.: max. 80°C at the cable gland When ambient temp. > 40°C heat resistant cable e. g. Sinotherm 110 H05GG-F 3G 1.5 mm2
must be used.
• Electrical data:
power supply 24 V or 120 V, halogen lamp 50 or 100 W,
2-pin socket GY 6.35
• Transformers: Transformers can be supplied as extra item.
• Combinations:
ESKS and SKS units can be combined with SW I type wipers
(see data sheet 02.01.)
• Mechanical fitting:The unit comes ready assembled. Before welding, the sight glass frame and the hinge assembly should be removed from the base flange. Check desired position i. e. direction of swing. The lug and hinged assembly holes are not identically spread. The weld flange must be welded into the vessel wall free of distortion; bolt-on flanges require an entirely flat vessel wall.

• Lamp change:
Since the unit must be opened for lamp change, reduce pressure
in the vessel to zero, and put vessel out of operation.
Check vessel for pressure and temperature before opening
a sight glass fitting!
