| Abstract: | An on-line measuring system was developed to detect and control the moisture content of pressboard during the drying process of large transformer body.Signals of moisture content sensed by a specially designed sensor in the drying pot were magnified and transduced,then the single-chip microcomputer processed the data and displayed them.Presented a hardware structure and a software design of the system,also gave anti-interference measures of the hardware and software. |
