Abstract: Differential resistance sensors are largely used to observe the stress, strain and temperature of hydraulic constructions in hydraulic and electric engineering which has been built. Owing to the long life-span constructions, it’s very vital to assess these embedded sensors. Some methods are proposed in this paper to discuss by the working principle and manner of differential-resistance sensors.

摘要: 差动电阻式传感器在已建水电工程中大量使用,用来观测水工建筑物的应力应变及温度,由于水工建筑物的使用寿命很长,因此对这些已埋设传感器的评定是个很重要的问题。本文依据差动电阻式传感器的工作原理及其工作方式提出评价的方法。差阻式传感器作为水工内部观测中的重要传感器,应该尽可能的了解其测量特性,以便获取准确的测量结果。
