Sensors & Applications Glass Industry

Sensors and measuring systems for glass production Modern glass production is determined by maximum efficiency. Therefore, rapid access to fundamental process variables is required in order to ensure fast control of the process. With products such as container glass, flat glass or special glasses, tight manufacturing tolerances must be adhered to while maintaining the shortest possible cycle times. Due to their high degree of integration as well as the high accuracy and measurement speed, sensors from Micro-Epsilon are used in the glass industry for different measurement tasks: robust inductive...

Flat glass

Thickness measurement of displays and flat glass For the production of display glass, glass sheets with a homogeneous thickness profile are required. White light interferometers from Micro-Epsilon are used for high precision thickness monitoring, which determine the thickness without contact and from one side. Due to their high measuring rate, the sensors are also applied in high speed processes. Edge control of glass sheets The exact positioning of glass sheets in the manufacturing process during separation is a prerequisite for the exact size of the glass pane. Two optoCONTROL 2700 micrometers...

Container glass confocalDT Confocal sensors for measuring displacement and thickness Small measurement spot size High repeatability Ideal for dynamic measurements

Measuring the wall thickness and roundness of bottles With the wall thickness and roundness measurements in star wheel inspection machines, a fast measuring rate is required in order to support the ongoing process. Micro-Epsilon’s confocal chromatic measuring systems provide a high measuring rate and fast exposure time control. This also enables the measurement of thickness when the glass colors vary. Sensor: confocalDT Thickness measurement of medical container glass Consistent thickness of walls and bottom are vital quality factors in medical container glass. In order to determine the glass...

In hollow glass production, IS machines are used. This production environment is characterized by harsh ambient conditions such as vibration, steam and high temperatures. Micro-Epsilon has developed an inductive EDS displacement sensor, which is specially intended for 24-hour operation in IS machines to determine the exact plunger position. The robust sensor design compensates for temperature influences, including those caused by temperature gradients along the measuring range. Distance control of print heads for glass printing When printing on materials such as glass and ceramics, very fine...

Camera autofocus measurement Confocal sensors measure the distances between the autofocus lenses to provide the camera with the highest possible image quality. Sensor: confocalDT Gap sizes of display glass and thickness measurement of multi-layer transparent materials While smartphone display glasses are fed automatically into the line, a fast thickness measurement is carried out. With the single display glass layers presenting different refractive indices, several glass layers can be measured using only one confocal sensor. Sensor: confocalDT Surface inspection of display glass Fully-automatic...
