    摘要： La présente invention a pour objet un dispositif de détection caractérisé en ce qu'il comprend :
    - un corps (1) définissant deux portions,
    - une interface de contact (2) avec un élément détecté, mobile en translation dans la première portion (1a) du corps (1),
    - au moins deux conducteurs (4a, 4b) dans la seconde portion (1b) pour former des broches de connexion (4a', 4b') à un circuit électrique et des bornes (4a", 4b") pour interagir avec un contacteur (7) déplacé sous l'action de l'interface de contact (2) et d'un moyen de rappel (8) en opposition,
    - un système d'étanchéité (9) pour éviter tout échange de fluide entre le milieu de l'élément détecté et un second milieu au niveau de la seconde portion (1b) du corps du dispositif, ce système d'étanchéité (9) étant traversé par les deux conducteurs (4a, 4b).

    摘要： A device for signalling the presence of pressure inside a plant, duct or similar space comprises a first part (1) provided with means (51) for the hydraulic connection to the plant, duct or space under control, a second part (2) axially sliding inside said first part (1) and a central pin (3) fixed inside said second part (2). The central pin (3) is run along by an axial bore (52) for the hydraulic communication of the plant, duct or space under control with a chamber (200) arranged above said second part (2). At least one transversal bore (6) of said central pin (3) places said axial bore (52) of the pin (3) in communication with a first chamber (300a) of said second part (2) arranged above said first part (1). A second wider chamber (300b) is interposed between said first part (1) and said second part (2) and an annular cavity (300c) places said first chamber (300a) in communication with said second chamber (300b).

    摘要： A pressure switch comprising an external force transmission mechanism separating a cover and a housing, a first pressure chamber sectioned by the cover and the external force transmission mechanism, and a second pressure chamber sectioned by the housing and the external force transmission mechanism. The second pressure chamber is provided with a movable piece having first and second movable portions located oppositely, and one or more fixed contacts. The first and second movable portions are coupled through a leaf spring. The second movable portion is provided with a contact functioning as a movable contact. When the external force transmission mechanism applies an external force to the first movable portion, the first movable portion is displaced, the second movable portion is reversed at the action point of the first movable portion, and thus the movable contact comes into contact with the fixed contact.

    摘要： An electromechanical pressure switch is described comprising a hollow body formed by a base (1) and a cap (9), between which an elastically deformable membrane (5) is clamped and closes a pressure sensing chamber (4) which communicates with an inlet hole (3) for a pressurized fluid, and lever means (15) for transmitting the deformation of the membrane (5) caused by the pressurized fluid to an actuating push button (22) of a switchable microswitch (23). The lever means (15) consist of a one-piece third-kind lever (15), comprising a first end bend (16) clamped together with said membrane (5) between said base (1) and said cap (9) and a flat part (18) which bears at the free end a projecting rib (21) for controlling said actuating push button (22) of the microswitch (23). The flat part (18) of the lever (15) is adjustably fixed to an adjusting screw (13) having an axis coinciding with that of the pressure switch which has a spherical tip (12) in contact with a central point (11) of the membrane (5).

    摘要： A differential pressure indicator has a housing with at least two ports in the housing. One port receives a first pressure, and the second port receives a second pressure. A pressure resistive device is placed between the first port and the second port. The pressure resistive device changes its position when the first pressure exceeds the second pressure by a predetermined amount. A magnet is coupled to the pressure resistive device. A digital displacement sensor senses the position of the magnet. The digital displacement sensor is in communication with an electronic indicator. The electronic indicator activates when the first pressure exceeds the second pressure by a predetermined amount.
