        張力傳感器的用途和測量方式

           張力傳感器的用途:用于測量在帶材上的實際張力負荷。張力傳感器反饋沒有帶材存儲功能,但是它提高了張力控制精度,縮短了響應時間,傳動速度或者轉矩由張力調節器調節。張力控制包括速度調節模式和轉矩調節模式。轉矩調節模式又可分為開環轉矩調節模式和閉環轉矩調節模式。轉矩調節模式可以使系統運行較穩定。
            張力傳感器的測量方式:張力傳感器采取電阻應變式丈量方法感應張力大小的變更,然后將其轉化為呈線性關系的直流電壓信號輸出。此電壓信號可經外部放大電路放大后輸送到數字式張力顯示器,其張力值能直接以磅、克、千克、牛頓等單位顯示出來,或將經放大的信號如0-10V,4-20mA等輸送到如PLC等節制器來進行張力實時把持。
