A method for detecting a high pressure condition within a high voltage vacuum device (402) includes detecting the position of a movable structure such as a bellows or flexible diaphragm (412) . The position at high pressures can be detected optically by the interruption or reflection (414) of light beams, or electrically by sensing contact closure or deflection via strain gauges. Electrical sensing is provided by microcircuits (1002) that are operated at high voltage device potentials, transmitting pressure information via RF or optical signals.
La présente invention concerne un procédé destiné à détecter une condition de haute pression dans un appareil à vide haute tension consistant à mesurer la position d~une structure mobile telle qu~un soufflet ou une membrane souple. La position à haute pression peut être mesurée optiquement par interruption ou réflexion de faisceaux lumineux, ou électriquement par détection d~une fermeture de circuit ou déflexion via des tensiomètres. Une mesure électrique est réalisée par des microcircuits fonctionnant à des potentiels d~appareil haute tension, avec transmission de données de pression via des signaux RF ou optiques.
