German HARTMANN Elektrotechnik sensors, HARTMANN Elektrotechnik models, HARTMANN Elektrotechnik prices

HARTMANN Elektrotechnik sensors are measurement feedback devices that operate based on the optical principles of gratings. Grating scales are frequently used in the closed-loop servo systems of CNC machine tools for detecting linear or angular displacement. The measurement output signal is a digital pulse, characterized by a large detection range, high detection accuracy, and fast response speed. For example, in CNC machine tools, they are commonly used to detect the coordinates of tools and workpieces to observe and track tool path errors, thereby compensating for tool motion errors. Grating scales are classified according to manufacturing methods
