Fields ofapplication
Monitoring of flow,filling level, condition,colour and gas contentsof media in pipes andvessels and near pumps.
The Richtersight glasses aredesigned• for media where stainless
steel is not corrosion-resistant
• as an alternative to valvesmade of expensive specialmetals (Hastelloy, Monel,tantalum, etc.)
• for pure and slightly solids-laden media
• for metal-reactive media,e.g. H2O2
• for pure media wheregood cleaning possibilitiesand anti-adhesive surfacesare important.
Operating rangeDepending on version andmaterial• from – 60 to +200˚C,
(–75 to + 400˚F), series SGS max. 150˚C (300˚F)• from vacuum to 16 bar
(235 psi)SGS max. 6 bar / 88 psi
• installation position horizontal to vertical
Product features• borosilicate glass to
DIN 7080• sight glass panes and
cover flanges to DIN3237-2, bolted individu-ally to the body
• large free field of vision• series SGS: cylindrical glass
with all-round vision
• DN 15-100 (1/2” to 4”) withdrip lip: also indicates verylow flow volumes
• rugged design withmetallic armouring
• thick wall lining with highpermeation resistance
• face-to-face lengthDIN EN 558-1 basic series 1(ISO 5752 basic series 1)
• flange connectingdimensions:DIN EN 1092-2, design B(ISO 7005-2, type B),drilled to ANSI Cl. 150 onrequest
• various options, see page 5
