    • The invention concerns a pressure sensor including: a micro-electromechanical vibrating device, comprising a silicon substrate (15') onto which a multilayer vibrating assembly (321) is formed; a control device (21') of said assembly in order to make it oscillate relative to said substrate at the resonance frequency or at another known frequency; and a detector for detecting the actual frequency and/or amplitude of said oscillation. Since said actual frequency and/or amplitude are affected by the conditions, in particular the pressure, of the external environment, the variations of said frequency and said amplitude with respect to the values set by said control device can be used to measure pressure variations in the surrounding environment.
    • 本发明涉及一种压力传感器,包括:微机电振动装置,其包括形成多层振动组件(321)的硅衬底(15'); 所述组件的控制装置(21'),以使其以共振频率或另一已知频率相对于所述衬底振荡; 以及用于检测所述振荡的实际频率和/或振幅的检测器。 由于所述实际频率和/或振幅受到外部环境的条件特别是压力的影响,因此所述频率和所述振幅相对于由所述控制装置设定的值的变化可用于测量压力变化 周边环境。

    • The present invention concerns a rotary vacuum pump (101) including a plurality of pumping stages obtained through the cooperation between alternate rotor discs (123) and stator discs or rings (115), at least one duct (135, 127) for introducing a gas or a gas mixture into the pump, said duct being interrupted by an electrically controllable valve (133), and an electronic control device (129) programmed to detect at least one operating parameter of the pump and to modify the configuration of said valve (133) so as to cause an increase or a decrease in the amount of gas passing through said duct (135) based on the detected value of said parameter. The invention further concerns a method of operating said pump, a pumping system including one or more such vacuum pumps and a method of operating said pumping system.
    • 本发明涉及一种旋转式真空泵(101),其包括通过交替的转子盘(123)和定子盘或环(115)之间的配合而获得的多个泵送级,至少一个用于将气体 或气体混合物进入所述泵,所述管道被电控制阀(133)中断,以及电子控制装置(129),其被编程为检测所述泵的至少一个操作参数并且修改所述阀(133 ),以便基于所述参数的检测值引起通过所述管道(135)的气体量的增加或减少。 本发明还涉及操作所述泵的方法,包括一个或多个这种真空泵的泵送系统以及操作所述泵送系统的方法。
