上文简单介绍了电阻应变式力传感器的工作原理,从中可以看出,弹性元件是传感器中将力P转换为应变ε的关键元件,电阻应变片是将应变ε变换为电阻值P变化的敏感元件。而整个测力传感器的结构型式取决于弹性元件受力变形方式。按弹性元件贴片部位变形方式划分,力传感器可分为拉压式(即承受拉压变 The above brief introduction of the working principle of resistance strain force sensor can be seen from which the elastic element is the sensor of the force P is converted to the key components of the strain ε resistance strain gauge is the transformation of the strain ε sensitive to changes in resistance P element. The structure of the entire load cell depends on the elastic deformation of the force components. According to the deformation of the elastic component patch area division, the force sensor can be divided into tension and compression (that is, under tension and compression change
