工作原理
双金属温度计的工作原理是利用二种不同温度膨胀系数的金属,为提高测温灵敏度,通常将金属片制成螺旋卷形状,当多层金属片的温度改变时,各层金属膨胀或收缩量不等,使得螺旋卷卷起或松开。
由于螺旋卷的一端固定而另一端和一可以自由转动的指针相连,因此,当双金属片感受到温度变化时,指针即可在一圆形分度标尺上指示出温度来。这种仪表的测温范围是200~650℃,允许误差均为标尺两程的1%左右。
概述
双金属温度计的英文名称是bimetal thermometer;bimetallic thermometer,是一种适合测量中低温的现场检测仪表,可直接测量各种生产过程中的液体、蒸汽和气体介质温度。
双金属温度计主要的元件是一个用两种或多种金属片叠压在一起组成的多层金属片,利用两种不同金属在温度改变时膨胀程度不同的原理工作的。是基于绕制成环性弯曲状的双金属片组成。一端受热膨胀时,带动指针旋转,工作仪表便显示出热电势所应的温度值。
