Glass production

Products such as container glass, flat glass or special glasses require tight manufacturing tolerances while maintaining the shortest possible production cycles. Due to the high degree of integration as well as the high accuracy and measurement speed, sensors from Micro-Epsilon are often used in the glass industry: robust inductive sensors are integrated into machines in order to detect machine movements while optical sensors monitor the glass products in processing lines. Typical measured parameters include displacement, position, thickness, colour and temperature.

Distance measurement onto anti-reflective coated glass

Anti-reflective coated glass is inspected during the coating process using laser-optical displacement sensors from Micro-Epsilon in order to determine undulations and torsion. The planarity of the coated glass surface is measured in several…
