Product Description

Applications

Rectangular Lumistar sightglasses of the series RSG / RSGR / RSGRR may beused to observe the interior of reactors, columns, silos, vessels,storage tanks andpipelines.They serve mainly as liquid level gauges.The are delivered ready to bewelded into or onto a vessel wall, complete with the appropriate seals, glass plates,and cover fastenings. 
Note: The nominal pressure indicated refers to the design base of thesightglass. When weided into the vessel concerned, the base frame becomespart of the vessel wall. It is necessary, therefore, that appropriate strengthcalculations are made on all vessels concerned with respect to the designpressure and size of the vessel and in accordance with the relevant designcode. If found to be necessary, reinforcement of the vessel wall has to becarried out. 

Operating temperatures: 
10°C max. with sodium silicate glass to DIN 8903 243°C max. with borosilicate glass to DIN 7081 Note: The above indicated temperatures refer to the use of unprotected glassplates, with no protective mica sheets. 
Operating conditions:Nominal pressure 16 bar.
Certificates: 
To be supplied against extra charge to DIN EN 10204. 

Standard materials: 
Base frame: RSt 37-2 or Hll (boiler plate) /AISI 316 Ti stainless steel 
Cover frame: As base frame Glass plate: Toughened sodium silicate glass to DIN 8903 (max.100 °C) Toughened borosilicate glass to DIN 7081 (max.243℃)
 Gaskets: KLINGERsil C4400 / NeoprenePTFE / Viton Cover fastenings: Steel, quality 8.8 / Stainless steel Other materials on request. 

Options: 
- Version with closed base frame (drawing left) to be used as an external liquid levelgauge with top and bottom pipe connections.For this application ,the base framewill be supplied appropriately drilled and tapped. 
- Radiused base frame to suit vessel wall 
- Clear (transparent) glass plate 
- Alternative versions in shape and size 
 

Remarks: 
The approval does not apply to the base flange as this is considered as part ofthe vessel wall after welding.Standard delivery includes a reflex(fluted) glass plate. lncircumstances where a clear (transparent) glass plate is required, this must be clearlystated at the time of enquiry. After welding into the vessel,the base frame should be checked to ensure thatthe sealing surface is flat and has not become distorted to avoid possible leakageunder pressure and / or breakage of the glass plate during tightening of the coverframe bolts. This process should be carried out in several steps and progressively alternating between each pair of opposite bolts from one end of the frame to the other!Tighten first little, then repeat the operation.
