Germany Dr Brandt sensor Dr Brandt model Dr Brandt price

Dr Brandt sensor is a measurement feedback device that operates based on the optical principle of gratings. Grating scales are frequently used in closed-loop servo systems of CNC machine tools and can be used 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 often used to detect the coordinates of the tool and workpiece to observe and track feed errors, thereby compensating for the motion error of the tool. Grating scales are classified according to different manufacturing methods and optical principles into
