SCA is a leader in the design, manufacture and installation of complete product inspection systems. In line with the high demands of end customers for product safety and quality, SCA uses its unique expertise and experience to develop advanced automated process and quality control systems.

Modern inspection systems in most cases involve the use of a visual inspection system integrated into the PLC control system. Such systems have high accuracy, high robustness, high reliability and high mechanical and temperature stability. Very often, on production lines, the visual inspection system performs hundreds or even thousands of component inspections per minute.

The use of inspection systems achieves, in the last resort, higher speed, accuracy and repeatability on production lines and machines.


When a customer presents us an inspection job, we consider the whole concept. First of all, is the job feasible? Will the benefits of implementing and introducing an inspection system be justified in terms of costs? Basically, does it make sense to introduce this type of technology at all?

If the work is estimate to be feasible, we look for samples for inspection, as well as pictures of machine parts, processes or installations. It is very important to have the right samples. In that sense, we get good, bad and samples with marginal defects. Samples with marginal defects are the most difficult for inspection, because we can accept them as good or bad. These samples/ defects determine the sensitivity of the system.

After that, we start preparing the elaborate. The elaborate includes testing the inspection system with collected samples using the most modern sensors (hardware) and software tools.

After the research, we give a proposal for the realization of the job, which is very often based on previous experiences on similar projects.

At the end of the study, we provide a final report on the feasibility of the system. The elaborate is not an additional cost for the project, because it is part of the development. Preliminary system testing removes the risk of the project and provides a better insight into the limitations of the system as well as the benefits of the application.

Industrial cameras

The industrial camera is a visual sensor and it is part of the technology we call the Machine Vision System (MVS). In the background of MVS is also software and hardware for image processing.

These three parts make the visual system as one compact unit.

The camera together with software tools for visual inspection of products (focus, shape matching, measuring tools, tools for reading characters and codes, logic functions, bar code verification) supports various industrial protocols (PROFINET, Modbus TCP, EtherNet/IP…) and has own input/output module. Therefore, the camera enables visual inspection as a stand-alone unit. So this type of camera is considered as a smart device.

Very often the camera alone is not enough, but it is easily to integrate it into the existing control system. As part of the control system, the camera decides whether a product has been inspected and whether it will be used in further production, thus affecting the operation of the machine, production line or the entire production process.
