We supply sight glass discs and gauge glasses resistant to high temperature, high pressure and comply with DIN8902, DIN7080, DIN7081.
The material we can supply includes soda lime glass, borosilicate glass, aluminosilicate glass and quartz glass with thickness 1-30mm, even can up to 1-85mm.
Sight glass, is a transparent, flat viewing pane installed in various industrial equipment to observe the fluid levels or processes within tanks, pipes, or vessels. It acts as a visual indicator, allowing operators to monitor liquids or gases in real-time.
Transparent flat gauge glass, also called transparent sight glass, transparent level glass and transparent level gauge, is usually made of borosilicate glass and aluminosilicate glass. The glass is manufactured into the strip shape and used in boiler or some instruments for observing the liquid level.
Reflex gauge glass, also named reflex sight glass, reflex level gauge glass, boiler glass and reflex level gauge.
One distinguishing feature of the Reflex Gauge Glass is its grooves. These grooves serve to enhance the refraction and reflection of light, improving the visibility of liquid levels. The result is a clearer, more accurate reading for operators, enabling better control and monitoring of liquid levels in various industrial applications.
WT GLASS offers different glass material options for customized sight glass and transparent flat gauge glass to meet specific customer’s requirements. Each material has its unique properties, and the choice depends on the specific requirements of the application.
Comply with DIN 8902, soda-lime sight glass can endure one-sided liquid to 150℃
It provides a superior surface quality and increased hardness, making it more resistant to scratching and wear and it resist to more higher pressure than borosilicate glass.
borosilicate glass material is the most common material used for sight glass due to its highly resistance to thermal shock and pressure, also resist to acids or alkalis. Comply with DIN7080 280°C
We can supply quartz glass of JGS1, JGS2 and JGS3 as per customers requirements. Max. 1000°C
