1、The Ninth International Conference on Electronic Measurement lasting 2 minutes and unloading to zero and waiting 2 minutes, adding 30g and wait for 5 minutes at last. The sensor output should be read respectively at

2、the times both when it has loaded and before its next load. Test data are as the table 1. The test result indicated a very satisfactory compensation. Creep compensation is not so popular way for many sensor manufact

3、urers. Some company abroad used a method, which is establishing math model and compensate creep using the model. This is a not so good way because of more expensive cost, large calculation and bad adaptability in dif

4、ferent environments. About mentioned fuzzy compensation for creep characteristic of weight sensor analyzed the creep and working condition of sensor, used the characteristic curves such as difference between slops of

5、 sensor creeps of loading and unloading, calculated change of present output of sensor using special functions, combined with dynamic fuzzy identification, find out the start and end of the creep for different loadin
