Polaris

Polaris series; high-precision, robust, flexible

The POLARIS series displacement sensors have proven successful in hundreds of difficult, high tolerance applications owing to their extreme precision and rugged reliability. They provide non-contact measurement of distance, thickness, width, height, or flatness, depending on the configuration, at a high measurement frequency. Thanks to their high-resolution CCD line array and the integrated Digital Signal Processor (DSP), they provide accurate measurement results for online process monitoring and control. Through tighter process control, return on investment (ROI) can be achieved within a short period of time.
The POLARIS series sensors provide precise results on virtually all materials at any production speed.
They automatically adapt to changing colours and surfaces. Even measurements on shiny aluminium, non-vulcanised black rubber, and on soft or sticky materials are possible.
