Make two pull at both ends of the part are respectively fixed together, drying oven with both ends of the transverse plane of action between sensor with clamping force, piezoelectric sheet in the region of the side pressure at the center of the piezoelectric patches, substrate part on the other side with the edge of piezoelectric patches, and close to the piezoelectric patches between power transmission parts. One of its purposes is made GouCheng to replace lever equation.
advantages
High precision, wide measuring range, long life, simple structure, good frequency response characteristics, can work in harsh conditions, easy to realize miniaturization, integration, and species diversity, etc.
disadvantages
For large strain is larger nonlinear, output signal is weak, but can take a certain amount of compensation measures.
