Abstract: A pressure sensor is a micro-electro-mechanical vibrating device, with a silicon substrate (15; 15′) onto which a single-layer or multilayer vibrating assembly (121; 221; 321) is formed. It comprises an electrode (21; 21′), which makes the assembly to oscillate relative to the substrate at the resonance frequency or at another known frequency, and a detector for detecting the actual frequency and/or amplitude of said oscillation. The actual frequency and/or amplitude are affected by the conditions, in particular the pressure, of the external environment and the variations of the frequency and amplitude with respect to the values set by the electrode is used to measure pressure variations in the surrounding environment.

Abstract: An electronic device for feeding an ion pump with two different tensions and for improved measuring of the pressure in the pump, the two different tensions being a normal operating tension and a lower tension at which a correct measurement of the pressure can be made in a pressure range up to beyond 10.sup.-10 torr. through a transformer whose primary or secondary winding is divided into two sections that can be connected and separated by switches controlled by oscillator circuits. Alternatively feeding at two different tensions can be obtained by feeding to the primary winding of the transformer a pulsed tension having a rectangular wave form and a high frequency controlled by a field effect transistor having an isolated gate. A sampling and holding circuit permits the pressure to be measured only in the conditions of feeding at the lower tension.
