稱重傳感器材料

應(ying)變片和電阻(zu)元件材料

應(ying)(ying)變(bian)片(pian)是(shi)(shi)稱重傳(chuan)(chuan)感(gan)器(qi)的(de)感(gan)應(ying)(ying)部分(fen)(fen)，是(shi)(shi)傳(chuan)(chuan)感(gan)器(qi)的(de)重要組成部分(fen)(fen)。它將外力的(de)大(da)小轉化(hua)為電學量輸出(chu)，是(shi)(shi)傳(chuan)(chuan)感(gan)器(qi)為重要的(de)組成部分(fen)(fen)，常(chang)用(yong)的(de)應(ying)(ying)變(bian)片(pian)基材(cai)(cai)(cai)采用(yong)高(gao)分(fen)(fen)子(zi)薄膜材(cai)(cai)(cai)料，應(ying)(ying)變(bian)材(cai)(cai)(cai)質通常(chang)為高(gao)純(chun)度(du)康銅 。應(ying)(ying)變(bian)片(pian)的(de)性(xing)能不僅僅與基材(cai)(cai)(cai)和康銅純(chun)度(du)有關(guan)，還與制造(zao)工(gong)藝有關(guan)。提高(gao)工(gong)藝技術水平也是(shi)(shi)改善傳(chuan)(chuan)感(gan)器(qi)性(xing)能一個很重要的(de)方面。
