工作原理
雙金屬溫度計(jì)的工作原理是利用二種不同溫度膨脹系數(shù)的金屬,為提高測溫靈敏度,通常將金屬片制成螺旋卷形狀,當(dāng)多層金屬片的溫度改變時(shí),各層金屬膨脹或收縮量不等,使得螺旋卷卷起或松開。
由于螺旋卷的一端固定而另一端和一可以自由轉(zhuǎn)動(dòng)的指針相連,因此,當(dāng)雙金屬片感受到溫度變化時(shí),指針即可在一圓形分度標(biāo)尺上指示出溫度來。這種儀表的測溫范圍是200~650℃,允許誤差均為標(biāo)尺兩程的1%左右。
概述
雙金屬溫度計(jì)的英文名稱是bimetal thermometer;bimetallic thermometer,是一種適合測量中低溫的現(xiàn)場檢測儀表,可直接測量各種生產(chǎn)過程中的液體、蒸汽和氣體介質(zhì)溫度。
雙金屬溫度計(jì)主要的元件是一個(gè)用兩種或多種金屬片疊壓在一起組成的多層金屬片,利用兩種不同金屬在溫度改變時(shí)膨脹程度不同的原理工作的。是基于繞制成環(huán)性彎曲狀的雙金屬片組成。一端受熱膨脹時(shí),帶動(dòng)指針旋轉(zhuǎn),工作儀表便顯示出熱電勢(shì)所應(yīng)的溫度值。
