SYSTEM AND METHOD FOR LOAD SENSING USING PIEZOELECTRIC EFFECT

摘要

System and method for measuring static load by using a piezoelectric load sensor with a feedback technique to compensate for the signal loss due to charge leakage, and therefore ensures measurement accuracy. The system is integrated with other structure, objects and devices to measure static loads applied to a mechanical shaft, in an on-line, in-process, quasi real-time fashion. The system can be used to measure static load and thus oversee an entire machine system or a manufacturing process.
