摘要：

An on-line monitoring system of vacuum pressure for 35KV vacuum tube is designed in this paper. The operation principle, hardware structure and software plan are explained in details. The system can valuate the internal pressure of the vacuum tube by monitoring the static charge of the shields using electrical field sensors with rotating electrode. At the same time, the data-collecting machine and the controller are developed for long-range and on-line monitoring. The result shows that such system runs steadily and reliably. It can estimate the vacuum degree accurately laying 35cm from the vacuum tube. Besides, it is steady and anti-jamming with less-cost.
