Inline measurement of width, thickness and temperature of plastic sheets
Inline measurement of width, thickness and temperature of plastic sheets: Laser distance sensors and infrared sensors enable precise, non-contact process monitoring in extrusion.
Diameter and thickness measurement on rotating workpieces
How does thickness measurement work with laser distance sensors? Learn how laser triangulation enables precise diameter and thickness measurements – even on rotating workpieces.
How can the thickness of plasterboard be measured during the production process?
How can the thickness of plasterboard panels be precisely measured inline? wenglor uses laser triangulation sensors from the P3 series for this purpose, which are non-contact, robust and work without an external analysis module. Two opposing sensors simultaneously measure the distance to the material surface and automatically calculate the exact board thickness – directly as an analog value or via IO-Link for the PLC.
How can the layer thickness of a bitumen-coated membrane be reliably measured?
Reliably monitoring the uniform layer thickness of bitumen-coated film webs is a key challenge in continuous production processes. The article shows how 2D/3D profile sensors and laser distance sensors from the P3 series enable precise thickness measurements across large web widths – over large areas or at defined measuring points – and thus ensure stable process and quality control.
How can I accurately measure the thickness of a medical fleece with alternating colors?
This question reached wenglor. The application’s challenge: the thickness measurement of the medical nonwoven must be continuous – even with changing colors. A task that is not so trivial in practice. This is because optical measuring methods often reach their limits as soon as the surface finish or color of the material changes. This is […]
