How It Works A measuring wheel is placed on the surface of the object being measured. As the object moves linearly, the wheel rotates, creating a rotary motion. An integrated rotary encoder detects this rotation and converts it into digital signals, which can then be translated into linear data such as speed or position (kuebler.com ). Features of the MWE21 Adjustable tension: Allows flexible adaptation to different applications and installation situations. Compact design: Ideal for use in tight spaces. Direct mounting: The measuring wheel with the attached encoder is mounted directly on the object surface, enabling precise measurement. Versatile applications: Suitable for conveyor technology, mechanical engineering, robotics, and other areas where linear motion needs to be accurately measured.
