Product catalog summary
Usage: MAXOS® safety sight glasses are designed for reliable monitoring of processes under thermal and chemical stress. They are made from borosilicate glass, known for its chemical resistance, purity, and low thermal expansion, making them suitable for high-temperature cycling resistance.
Application Properties: The glasses undergo production and quality inspections to ensure property values and dimensional tolerances, allowing them to be used in extreme conditions.
Fracture Behavior: Thermally pre-stressed borosilicate glass shatters without sharp edges, similar to safety windshields.
Chemical Resistance: The glasses can operate continuously at 280°C, up to 300°C for 300 hours, and 320°C with mica protection. They have a coefficient of expansion of 4.1 x 10⁻⁶ K⁻¹ and an elastic modulus of 67 x 10³ N/mm².
Dimensional Tolerances: Based on DIN 7080, tolerances are specified for sight glass plates, with permissible bubble defects outlined.
Standard and Special Dimensions: The document lists various dimensions and corresponding permissible pressures for MAXOS® sight glasses, adhering to DIN 7080 standards.

Round sight glass plates DIN 7080-1

Round sight glass plates DIN 7080for circular sight glass fittings DIN USAGE MAXOS® safety sight glasses are used wherever processes in container or flow sight glasses need to be reliably monitored under thermal and chemical stress.They enable safe visual inspection and contribute significantly to process control and safety. The high durability of these sight glasses is based on a special borosilicate glass, which is characterized by excellent chemical resistance, extraordinary purity, and high homogeneity. Thanks to the characteristic low thermal expansion of borosilicate, the glass can be thermally pre-stressed (tempered), giving it particularly high temperature cycling resistance. This combination of material properties and thermal treatment makes MAXOS® sight glasses a safe and durable solution for demanding industrial applications. Through production and quality inspections in the process flow, the property values of the glasses and the tight dimensional tolerances are guaranteed. With these excellent safety features, MAXOS® safety sight glasses can be used in extreme conditions. Operating conditions according to DIN 7080: 1) Only in combination with MAXOS® safety sight glasses Technical information CHEMICAL RESISTANCE Chemical resistance FRACTURE BEHAVIOR In the adjacent images, the fracture behavior of thermally pre-stressed borosilicate glass can be seen. It shatters without leaving sharp-edged break pieces. The glass break resembles a safety windshield in a car or safety glass. 17092025 - Subject to technical changes and errors!
