SICK has released the Profiler profile sensor. The device lays down a line of light over the profile to be measured and detects deviations from the defined measurement tolerance. It can still do this if the height of the object in the measurement field fluctuates for process-related reasons. The Profiler is mainly used for automating industrial production and testing processes.
It is designed as a standalone device with integrated evaluation. It operates like a single-line camera system with the functionality of a photoelectric switch, as it requires no separate illumination or external evaluation computer.
Laser optics generate a 30mm long line of light over a target object, such as a line of glue or an opening, at operating distances of 100mm ±25mm. Its permits distance-independent profile detection.
Its colour display shows what the 2D receiver element has detected and permits precise adjustment of the sensor. Even difficult profiles can be detected with great accuracy as a result of the device's high resolution in the micrometer range.
The three switching outputs and the 4mA-20mA analogue output provide the downstream plant controller with the measured values required for determining position or for a quality assessment. Rapid, precise and economical monitoring of height profiles is necessary in many applications. Applications include checking for gaps in automobile bodywork, inspecting profiles and welded joints, guiding robots, checking the content of blister packs or deep-frozen packaging, or monitoring filling heights.
A smaller number of reception elements need to be evaluated in the profiler than in camera solutions, allowing the rapid processing and evaluation of profiles, making the device suitable for use in high-speed processes and plants.
