Structure and working principle of grating displacement sensor
Grating displacement sensor if you have contact with it? Grating displacement sensor main play its role in the servo system, the working principle and the product structure grating displacement sensor is what like? The following Chinese sensor trading network of experts to tell you about the principle and structure of products grating Displacement Sensor.
Grating, also referred to as grating displacement sensor (encoder sensor), is the use of an optical grating feedback device measuring principle. Scale often used in CNC machine tools, closed-loop servo system, it can be used as the linear displacement or angular displacement detection.
The measurement signal into a digital pulse output with detection range, high precision, fast response characteristics. For example, in CNC machine tools often used to coordinate the tool and the workpiece is detected, and to observe the effect of motion tracking error error passes to play a compensation tool.
