Distance and angle measurement

Distance and angle measurements are found in almost every industrial sector, as they play a central role in the precise recording of lengths, positions, fill levels, and rotational movements, to name just a few examples. Whether in manufacturing, robotics, automation, or quality assurance, accurate measurements are essential for efficient processes, high product quality, and safe machine control. With the help of various measuring principles, both linear and rotary movements can be recorded, with the exception of distance-measuring fill level controls, which ultimately makes displacement and angle measurement systems an indispensable link between mechanical processes and digital control technology.

Against this backdrop, determining distances and angles is by no means a trivial matter. Anyone who considers the wealth of potential applications for such solutions will usually recognize the full complexity associated with a wide variety of tasks. Here are just a few examples of distance measurements: monitoring and controlling travel distances in automation and logistics, positioning tools on machines and systems, checking the diameter of coils, monitoring press-fit and joining processes, checking fill levels and distances in tanks or containers, and so on. The areas of application for angle measurement are equally diverse: position detection and control in automated processes, monitoring of bending process equipment, control of tilting devices in metalworking, positioning and leveling of mobile construction, work, and agricultural machinery, adjustment of tools and machine axes, etc.

Right now, the question basically arises as to how, given the wealth of possible applications, the right and therefore optimal technology for path and/or angle measurement can always be selected. In addition, many applications also require the corresponding solutions to have very specific properties, e.g., insensitivity to dirt, moisture, temperature, and vibrations, high precision and ranges, high dynamics and travel speeds, measurements independent of material properties, high flexibility, easy integration, easy installation, easy operation, and so on.

This white paper presents a wide variety of methods and devices for distance and/or angle measurement from ipf electronic and can therefore provide initial guidance for selecting a suitable technology for a specific application. In this context, it also becomes clear that there are sometimes lesser-known approaches to distance and angle measurement, which are also shown here.
