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‌。轴向型双金属温度计的指针盘与保护管呈垂直连接。这种安装方式使得测量响应速度快、抗干扰能力强, 适用于测量温度空间大且温度变化较均匀的场合。它特别适合于需要快速响应和稳定测量的环境, 如动力工程、机械制造等领域‌。

产品定位:

轴向型

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。
