Abstract	In order to measure the internal pressure by the traditional magnetron method, the vacuum tubes must be detached from interrupters and put into a solenoid coil. Thus, when the interrupters are to be refitted, their mechanical parameters must be readjusted by professional workers. In this paper, a new type of magnet coil is developed. Putting this coil onto the vacuum tube's side, and without detaching the vacuum tube from the interrupter, we can measure the internal pressure of the vacuum tube by the magnetron discharge method. Meanwhile, the measuring sensitivity of internal pressure is improved by an application of 80C196 micro-controller. Furthermore, the on-line detection of the internal pressure is a hard nut to crack. In this paper, by detecting the potential of the shield with a Pockels electric fields sensor, an on-line internal pressure detecting system is developed, and its mechanism is discussed.
