　　WSS溫度(du)(du)計是利用(yong)兩種(zhong)(zhong)不同金(jin)(jin)屬(shu)在(zai)(zai)溫度(du)(du)改(gai)變(bian)時(shi)膨脹(zhang)程度(du)(du)不同的(de)原理工作的(de)。工業用(yong)WSS系列溫度(du)(du)計主要(yao)的(de)元件(jian)是一個用(yong)兩種(zhong)(zhong)或多(duo)種(zhong)(zhong)金(jin)(jin)屬(shu)片(pian)(pian)疊壓在(zai)(zai)一起組成(cheng)的(de)多(duo)層金(jin)(jin)屬(shu)片(pian)(pian)。為提高測(ce)溫靈敏度(du)(du)，通常將金(jin)(jin)屬(shu)片(pian)(pian)制(zhi)成(cheng)螺(luo)旋(xuan)卷形(xing)狀。當多(duo)層金(jin)(jin)屬(shu)片(pian)(pian)的(de)溫度(du)(du)改(gai)變(bian)時(shi)，各層金(jin)(jin)屬(shu)膨脹(zhang)或收縮量不等(deng)，使(shi)(shi)得螺(luo)旋(xuan)卷卷起或松開(kai)。由于(yu)螺(luo)旋(xuan)卷的(de)一端固定而另一端和(he)一可(ke)(ke)以自(zi)由轉動的(de)指針相連，因此，當雙金(jin)(jin)屬(shu)片(pian)(pian)感受到溫度(du)(du)變(bian)化時(shi)，指針即可(ke)(ke)在(zai)(zai)一圓形(xing)分(fen)度(du)(du)標尺上指示出(chu)溫度(du)(du)來。這種(zhong)(zhong)雙金(jin)(jin)屬(shu)溫度(du)(du)計儀表的(de)測(ce)溫范圍(wei)是200~650℃，允許誤差均為標尺兩程的(de)1%左(zuo)右。這種(zhong)(zhong)溫度(du)(du)計和(he)棒狀的(de)玻璃液體(ti)溫度(du)(du)計的(de)用(yong)途相似，但可(ke)(ke)使(shi)(shi)用(yong)在(zai)(zai)機械強度(du)(du)要(yao)求更(geng)高的(de)條(tiao)件(jian)下。
