                        • 3D measurement technology - Xiris Vision Systems for Weld Inspection

                        • Weld seam and profile geometry inspection for pipes and profiles

                          Xiris systems use high-resolution laser-based 3D imaging system technology and fast data acquisition and analysis rates to enable real-time detection of welding defects up to 0. 015 mm in size.

                          These systems are used for precise 3D inspection to detect quality problems in forming and welding processes in pipe and profile rolling mills.

                          The production of welded pipes and lines requires the monitoring of several key parameters to ensure efficient, stable production and to meet quality requirements. Measurement/monitoring is the first step to control these parameters and improve welding quality.

                          Defects investigated include mismatch, undercut, sunken welds, bead height, deflection, etc.

                        • 3D measurement technology - DIC-Systems

                        • DIC systems (digital image correlation) can be used very flexibly regardless of the shape, temperature and size of the measuring object and can measure strains in the microstrain range (sub-micrometers) using microscope optics, as well as strain factors of several 100%, or even extreme measurement rates with high-speed cameras. Using the method of digital image correlation (grey value correlation, near-field photogrammetry), they can be used for both 2D and 3D applications. Typical applications from industry and research are motion and deformation analysis, material characterization, component testing and photogrammetric measurements. Measurements include tensile, compressive and bending tests, impact and pressure wave analyses, crack detection, fluid-structure interaction, fatigue analysis and under-surface defect detection.

                          Polytec offers two 3D DIC systems that complement each other perfectly:

                          • The StrainMaster Portable System, consisting of individual components, can be optimally configured for any application and offers maximum flexibility.
                          • The StrainMaster Compact System impresses with its compact, integrated design with minimal setup time and easy operation at a particularly low price.

                        • UV Technology

                        • Polytec offers UV systems and components for industrial and research applications in different technologies - from pulsed or continuous LED lights, arc or gas discharge lamps to UV-sensitive industrial cameras.

                           

                        • Fiber-Optic Measurement Technology

                        • At Polytec, fiber-optic measuring technology is split into two fields: “fiber-optic sensing technology” and “optical telecommunication / fiber-optic measuring devices”.

                          Fiber-Optic Sensing Technology:

                          Fiber-optic sensor systems use specific optical properties of materials – and often even the fiber itself – to measure physical variables such as temperature, strain or vibration. Extremely flexible solutions can be created in this regard: they range from the single-point measuring system, over individually defined spots along the fiber, to continuously measuring systems with a resolution of 1 mm across optical fibers that run for kilometers. A single fiber weighing just a few grams can therefore contain thousands of sensors and serve as a signal path at the same time. Because light is used as the transmission medium in the glass fiber, applications that remain off-limits to electrical sensor technology – such as in HF and microwave fields, high-voltage environments, potentially explosive atmospheres, chemically aggressive environments and much more besides – are indeed a possibility.

                        • Special Cameras

                        • Camera Systems for Every Application

                      • Process Analytics

                      • Analyzing ingredients and optimizing processes

                        Process analytics is used to optimize the production process, to ensure consistent product quality and, last but not least, to meet environmental requirements. The objective in this regard is to improve product quality and enhance efficiency with a view to reducing costs, saving time and cutting emissions. Automated real-time control allows for controlled interventions to be made even during the product manufacturing process. Costly and time-consuming faulty production operations are prevented as a result.

                        Process analytics can be used throughout the entire production chain: when inspecting incoming goods, during production (either online in the form of automatic sampling while bypassing process control, or inline in the form of automatic sampling directly during process control) and during final product control.

                        As they are easy to use and robust, spectroscopic methods – particularly near-infrared (NIR) spectroscopy based on dispersive diode array technology – are a popular choice in this area of application.

                        The available measured variables are diverse in this regard:

                        • Qualitative and quantitative compositional analyses to determine the concentration of products, additives and by-products, and to identify process-specific substances
                        • Physical parameters in both the reactor and the reaction mixture, such as the humidity level
                        • Layer thickness measurement

                          • Process Spectrometers - NIR Spectrometers

                          • Polytec PAS spectrometers provide the ideal solution to your NIR process analytics problems. Diode array detector technology combined with a transmission grating design means the devices can be used for fast and reliable data acquisition.

                          • The PAS-H-A03 distance sensor head is a reflection sensor head that allows the user to carry out sample measurements at distances of between 150 and 600 mm. This makes it ideal for analyzing goods being measured on conveyor belts, for strip products and for similar applications.
