应变传感器

奇石乐的压电应变传感器用于高分辨率测量结构上的应变。

奇石乐压电应变传感器可用于高精度测量结构上产生的应变。为此，需要将传感器安装在合适的位置。如果需要进行间接力测量，则需要对传感器进行校准。需要考虑的因素包括结构的几何形状、材料的弹性模量和机械应力。表面应变传感器通过安装螺钉固定在结构上。结构的应变通过静摩擦力传递给测量元件。应变测量栓需要一个圆柱形安装孔，然后将应变传感器插入其中并进行预载。奇石乐提供的压电应变测量传感器可与孔的轴向和径向对准。

Frequently asked questions

用于测量应变的压电传感器和应变传感器有何不同？

压电传感器具有极高的灵敏度，可进行高动态测量，几乎不需要任何位移。因此，单个传感器就能覆盖较大的测量范围，还能测量高刚性机械结构上的应变。另一方面，应变片需要至少很小的变形，通常设计用于非常特定的力测量范围。

如何为特定应用选择合适的应变传感器？

在选择应变传感器时，请考虑测量范围、灵敏度、精度和环境条件等因素。奇石乐技术专家可以帮助您选择最适合您需求的传感器。

如何正确安装应变传感器？

应变传感器主要用于间接监测应用。既可以安装在表面，也可以作为针脚安装在材料中。无论哪种情况，都应确保安装位置的材料中存在与要监测的相关过程直接相关的机械应力。有关安装和校准的详细信息，请参阅数据表。
