WSS 系列双金属温度计是一种适合对流体蒸气的中低温度进行直接测量的测温仪表。
双金属温度计对温度的测量是通过系统内部的由双金属材料制成的螺旋弹簧式双金属片对温度的传感来实
现的。其双金属材料是由两个不可分割的金属片所组成,因为两个金属的片的热膨胀系数不同,因而在温度变
化情况下会发生不同程度的伸展变形。这种伸展变形与温度近似成正比。金属片一端固定而另一端与指示轴固
定为一体,从而在金属片伸展变形时驱动指示轴旋转并在刻度盘上指示出相应的温度值。
WSS series bimetallic thermometers are designed to directly measure low and medium temperature of fluid
steam.
The sensing element "Bimetallic Coil" is composed of 2 indivisible metal sheets. Since the 2 metals have
different rates of thermal expansion, the bimetal deforms varying with temperature. This expansion is almost in
proportion to temperature. The one end of bimetal is fixed, the other end is connected to mechanism to drive
pointer.
