Features
- Dual symmetrical viewing window structure enables comprehensive two-side visual inspection, allowing multi-angle observation of fluid flow, bubbles, suspended particles and liquid mixing status for accurate process monitoring. Integral mirror-polished stainless steel body features a streamlined smooth flow path with extremely low fluid resistance, ensuring stable delivery speed without affecting overall pipeline production efficiency. Standard tri-clamp quick connection allows fast tool-free disassembly, facilitating daily internal inspection, window cleaning and gasket replacement with low maintenance difficulty. Adopts high-strength tempered glass viewing windows, which deliver excellent pressure resistance, high and low temperature stability and medium corrosion resistance, resisting cracking and deformation in long-term complex working conditions. Dead-zone-free smooth inner cavity effectively avoids material retention and residue buildup, fully adapting to CIP online cleaning to maintain long-term pipeline sanitation and viewing clarity. Compact and reasonable overall structural design fits directly into straight pipeline sections with simple and fast installation, suitable for various compact hygienic piping layouts.
Working Principle
Sanitary Double Window Sight Glass enables multi-angle visual inspection through symmetric glass windows on two sides. Medium flows horizontally through central flow channel of sight glass body. Operators can observe fluid color, flow rate, bubbles and suspended matters from both sides. Glass windows are sealed and compressed by stainless steel body to prevent leakage under pipeline pressure. During CIP cleaning, flushing liquid passes through cavity and removes deposits on inner glass surface to maintain clear view for continuous monitoring.
