How can distance measurement be reliably implemented on dark and reflective solar cells?
Precise distance measurement on dark and highly reflective solar cells poses challenges for many production plants. The article shows how blue laser triangulation sensors provide stable readings even on challenging surfaces, thus enabling reliable positioning in solar cell production.
How can the diameter of pipes be reliably measured while moving?
With 2D/3D laser sensors or punctual triangulation sensors, pipe diameters can also be reliably measured while driving. Robust, non-contact systems detect even rough surfaces and document precise expansions.
Can the direction of a jump be recognized from the change in the sign of the measured value?
The direction of a height or position jump can be reliably determined based on the change in sign during differential measurements. The article shows how two correctly referenced and aligned P3PC sensors can detect even small steps and reliably derive the direction of movement of the test object.
Presence check of flat parts under 1 mm
Precise presence check for flat parts under 1 mm: Distance Sensors reliably detect height differences of just 0.66 mm.
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.
Which sensors are suitable for detecting clear glass?
Which sensors reliably detect clear glass? This article explains the most important technologies for transparent materials – from retro-reflex sensors with polarizing filters and ultrasonic sensors to ToF and triangulation sensors. Find out which solution is best suited for glass, PET or film and how wenglor sensors reliably detect even highly transparent objects.
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.
Reliable thread detection with reflex sensors
The P1MH202 reflex sensors with background suppression reliably detect threads up to M6 regardless of color, surface and degree of gloss. A precise solution for automated inspection processes in production.
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 […]
