测量原理:

‌双金属温度计的测量原理‌是基于两种不同热膨胀系数的金属在温度变化时产生的形变差异。具体来说, 双金属温度计利用两种线膨胀系数不同的金属组合在一起, 一端固定, 当温度变化时, 两种金属的热膨胀不同, 导致双金属片弯曲, 这种弯曲通过传动机构带动指针偏转, 从而指示温度‌。

产品定位:

万向型

使用场景:

双金属温度计广泛应用于石油、化工、机械、船舶、发电、纺织、印染等工业和科研部门, 因其无汞害、坚固耐用、易读数等特点, 常用于需要高精度测温的场合。万向型双金属温度计的指针盘与保护管连接角度可以任意调整。这种安装方式提供了更高的灵活性,适用于中低温现场检测, 可以直接测量气体、液体、蒸汽的温度, 且显示清晰、机械强度好。它特别适合于需要频繁调整或在不同角度测量的环境, 如食品工业、工厂建设等领域‌。
