The gravity sensor works according to the principle of the piezoelectric effect. The so-called piezoelectric effect is “For a heteropolar crystal without a symmetry center, the external force applied to the crystal will not only deform the crystal, but also change the polarization state of the crystal. , An electric field is established inside the crystal, and this phenomenon of polarizing the medium due to mechanical force is called the positive piezoelectric effect.

The gravity sensor of precast concrete production line making machine uses the characteristic of crystal deformation caused by acceleration inside it. Since this deformation will generate a voltage, as long as the relationship between the generated voltage and the applied acceleration is calculated, the acceleration can be converted into a voltage output. Of course, there are many other ways to make acceleration sensors, such as capacitance effect, thermal bubble effect, and light effect, but the most basic principle is that a certain medium is deformed due to acceleration, and the deformation is measured and converted into voltage output.
