Tips: What is a digital displacement sensor?

A digital displacement sensor is a high-precision measuring tool that accurately converts the displacement of an object into a digital signal output. It can be used to detect minute changes in thickness, height, gaps, and other minute parameters. Its core feature is that the digital signal output is a discrete digital code, giving the signal high anti-interference capability and high resolution, facilitating direct connection to control systems or data acquisition equipment for automation and precision control. Therefore, digital displacement sensors are widely used in machining, industrial automation, quality inspection, and materials testing.
