Genuinely new equipment category — no sight glass exists elsewhere in the corpus. Shared: housing EN-JS 1049, flanges to ISO 7005-2 Type B or ASME B16.5 Class 150 raised face, EU PED 2014/68/EU and TA-Luft. Assigned to Sensing & Control because the function is process observation; a Piping & Fittings assignment is equally arguable (flanged in-line body, no powered output) — flagged as a taxonomy judgment, not a data finding. Selection rule: PSG or TSG for in-line process sight-checking, SGS for tank level visualization.

| Richter SGS design option | Cavity-free design option usable as a level indicator | richter-ct-sight-glasses.md |
SGS trades a lower pressure rating (6 bar vs. 16 bar) and a narrower temperature range for a cavity-free design that doubles as a level indicator — a real functional tradeoff to flag before specifying it for a high-pressure in-line sight-check application it isn't rated for.
A sight glass is a genuinely distinct equipment category for process observation, not a powered instrument, but the material and pressure choice still has to match the process — Richter's PSG and TSG both hold 16 bar at up to 360°F for in-line process sight-checking, while the SGS trades pressure and temperature range for a cavity-free design that can double as a level indicator.

FAQ
Is Sight Glass used in Chemical Processing?
Genuinely new equipment category — no sight glass exists elsewhere in the corpus. Shared: housing EN-JS 1049, flanges to ISO 7005-2 Type B or ASME B16.5 Class 150 raised face, EU PED 2014/68/EU and TA-Luft. Assigned to Sensing & Control because the function is process observation; a Piping & Fittings assignment is equally arguable (flanged in-line body, no powered output) — flagged as a taxonomy judgment, not a data finding. Selection rule: PSG or TSG for in-line process sight-checking, SGS for tank level visualization. This is strong evidence.
What products are specified for Sight Glass in Chemical Processing?
Documented examples include Richter PSG (standard flanged, DN25-DN150, 16 bar, -60°C to +180°C / -75°F to +360°F, DIN 3237 part 2, integrated drip lip, individually exchangeable cover flanges, borosilicate panes to DIN 7080; PSG/F in PFA, PSG/F-L antistatic PFA), Richter TSG (standard flanged, DN25-DN80, 16 bar, -60°C to +180°C; TSG/F, TSG/F-L), Richter SGS (cylindrical, DN15-DN100, 6 bar, -60°C to +150°C, viewing from all sides, cavity-free design option; SGS/F, SGS/F-L) — confirm current specifications with the manufacturer before final selection.
