This movement is transmitted to the potentiometer, which converts the length variation into an electrical signal and sends it to the output device.<\/li>\n\n\n\n<li>By applying a conversion factor, this output signal can easily be converted back into the length displacement. The difference between the initial and current measurement values represents the displacement, allowing easy monitoring of the rate, ratio, and trend of the joint\u2019s change.<\/li>\n<\/ul>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"439\" height=\"294\" src=\"https:\/\/foredencnc.com\/wp-content\/uploads\/2025\/11\/Screenshot-2025-11-05-233824.png\" alt=\"\" class=\"wp-image-90\" srcset=\"https:\/\/foredencnc.com\/wp-content\/uploads\/2025\/11\/Screenshot-2025-11-05-233824.png 439w, https:\/\/foredencnc.com\/wp-content\/uploads\/2025\/11\/Screenshot-2025-11-05-233824-300x201.png 300w\" sizes=\"auto, (max-width: 439px) 100vw, 439px\" \/><\/figure>\n<\/div>\n\n\n<h3 class=\"wp-block-heading\"><br><strong>Composition &amp;
