Consolidate your basic knowledge or learn something new – our basic knowledge provides you with the most important fundamentals of sensor technology, Machine Vision and smart automation.
Modern sensor technology enables non-contact level measurement for liquids, bulk materials or material rolls – precisely, reliably and independently of material, surface or medium.
Laser light differs from ordinary light in terms of focusing, coherence, and monochromaty. These features make it ideal for precise industrial measurements, scanners, and distance sensors.
Lasers enable the highest precision – but how safe is it to handle them? An overview of all laser classes according to EN 60825-1 shows what hazards exist and why wenglor only uses safe lasers of classes 1 and 2.
Triangulation sensors and time-of-flight sensors (ToF) offer different strengths in industrial automation: precision at short distances or robust measurement over long distances. Depending on the application – from micrometer-accurate short-range measurements to fill level control at 100 m – the right technology ensures reliable results.
RFID or barcode? We explain the differences, advantages and typical areas of application of both technologies – for efficient and automated identification processes in industry and logistics.
Reflex sensors detect objects without contact and provide precise switching signals. Depending on the application, triangulation sensors, time-of-flight or energetic reflex sensors are used – for high precision, flexibility and robustness in industrial automation.
Machine vision controllers centrally process image and profile data from several sensors, while smart devices take over the evaluation directly in the sensor. Both solutions enable flexible and efficient machine vision – depending on the complexity of the application.
Which type of light is suitable for which sensor application? Find out when red light, blue light, infrared, laser or ToF sensors are the best choice – for dark objects, long distances or difficult surfaces.
AI models and neural networks form the basis of modern industrial image processing: They detect objects, classify errors and make decisions automatically – intelligently, adaptively and future-proof.
RGB contrast sensor P1PW specifically detects colors, color families and fine nuances. Ideal for print marks, color control, and changing object colors.
The range of RFID readers depends on physical, technical and environmental factors. With targeted adjustment of the RSSI value via IO-Link, transponders can be reliably detected and processes efficiently controlled.
Artificial intelligence is revolutionizing industrial image processing: classification, object detection, segmentation and deep OCR enable precise, automated quality controls – faster and more reliably than ever before.
Ultrasonic sensors reliably detect transparent, dark or shiny packaging. Why they are ideal for changing materials in packaging and logistics.
What is an image chip and how does it work? This article explains how image sensors convert light into digital information, why CMOS sensors are standard today and what role sensor size and pixel architecture play in image quality. You can also find out when color sensors make sense and why monochrome chips offer clear advantages in industrial image processing.
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.
Smart Cameras and Vision Sensors are indispensable in industrial image
Colors are created by the interaction of light and the reflective properties of a surface. The article explains how colored materials reflect and absorb light – and how modern sensors use this information to precisely detect colors. Ideal for use in quality control, robotics and color measurement.
AI-based image processing makes the automatic recognition of best-before dates efficient and reliable. The Smart Camera B60 with Deep OCR reads best-before dates without errors, even with glossy films, irregular surfaces and high production speeds – for maximum quality assurance and process control.
Precise image processing starts with the right optics: when is a C mount lens the best choice – and when is auto-focus worthwhile? Find out which camera optics are optimal for your industrial application and how wenglor Smart Cameras combine the highest image quality and flexibility.
