Transparent glass has smooth surfaces on both sides and is suitable for applications with aggressive media, as it can be combined with mica protection discs. Reflective glass, on the other hand, has grooves on the medium-facing side, which enhance visibility of the liquid level through the difference in refractive indices between liquid and gas. Reflective glass is often used in closed fittings for clear level indication.
In thermal tempering, glass is heated to high temperatures and then rapidly cooled, creating internal stresses that enhance strength and temperature change resistance. This method provides safer fracture behavior, as the glass breaks into small, blunt fragments. Thermally tempered glass is particularly suited for process observation, as it offers higher pressure and scratch resistance. Borosilicate glass and soda-lime glass can be thermally tempered, while quartz and sapphire glass cannot.
These circular sight glass panels made of borosilicate glass are thermally tempered and specifically designed for use under high pressure, thermal, and chemical stress. They are characterized by high temperature cycling resistance and chemical resilience, and are manufactured under strict production and quality controls. These glasses are excellent for extreme conditions and ensure safety and reliability.
These long sight glass panels made of thermally tempered borosilicate glass are particularly suitable for use under pressure, as well as in thermally and chemically demanding environments. They provide high thermal cycling resistance and chemical durability and undergo strict production and quality controls. These glasses are ideal for use in extreme environments and ensure maximum safety and longevity.
This glass is used for applications with low thermal and chemical stress under pressure to enable visual inspection in containers. It withstands temperatures up to 150 °C, with the pressure depending on the diameter and thickness. Soda-lime glass has moderate resistance to water, acids, and alkalis, and the permissible material defects are standardized according to DIN 8902.
BOROFLOAT® sight glasses are used where a visual inspection of processes is necessary under pressure as well as thermal and chemical loads. They are characterized by a low expansion coefficient and high temperature resistance, but without thermal pre-tensioning. These glasses are durable and ideal for extreme conditions and applications that require high temperature cycling resistance.
These sight glass plates are made of pure SiO2 and are particularly suitable for applications with high thermal and chemical stress, such as in precision optics, laser, and electronics industries. They can withstand permanent temperatures of up to 1000 °C and temporarily up to 1200 °C, offering the highest chemical resistance. Production is carried out with tight dimensional tolerances to ensure reliable performance under extreme conditions.
Sapphire glass is extremely resistant to extreme thermal and chemical stresses and is ideally suited for applications that require visual inspections at high temperatures and with aggressive media. It consists of 99.997 % Al2O3 and offers excellent UV transmission as well as temperature resistance up to 2000 °C. Sapphire glass is used in demanding environments due to its optical and mechanical properties.
These pipes and capillaries are particularly resistant to chemical and thermal stresses and allow visual inspection of processes in pressurized pipelines. Thanks to the low coefficient of thermal expansion, Borosilicate glass 3.3 offers high temperature cycling resistance and is suitable for applications up to 300 °C. Strict production and quality controls ensure the durability and accuracy of this glass for industrial applications.
