| Abstract: | A new temperature compensation method based on software for vibrating wire sensor is introduced in this paper. The compensating circuit is given as well. Compared with the traditional compensation method based on hardware, the new temperature compensation method has advantages of simple hardware structure, strong anti- interference capability and high- precision. Experiment results indicated that the new method can reduce the influence of temperature during vibrating wire being measured and improve the precision. |
