Title (EN) FAILSAFE INTEGRATED TRANSDUCER
(FR) TRANSDUCTEUR INTÉGRÉ À SÉCURITÉ INTÉGRÉE
Abstract:
(EN) A transducer with a lower housing assembly and an upper housing assembly is for connection to a fluid pressure source having a mechanism for setting a pneumatic output via an electrical input signal. The lower housing assembly comprises lower housing configured to receive a supply nozzle, which fluidly communicates with a supply port and intermittently fluidly communicates with an output port of the lower housing through an internal fluid passageway. The lower housing further comprises an exhaust nozzle fluidly communicating with an exhaust port and intermittently fluidly communicates with the output port of the lower housing through the internal fluid passageway. The upper housing assembly comprises an upper housing configured to receive a coil and an armature such that the upper housing, coil and armature define a latching electromagnetic circuit that provides alternating contact of the armature with the supply nozzle and the exhaust nozzle of the lower housing assembly.
(FR) L'invention concerne un transducteur doté d'un ensemble boîtier inférieur et d'un ensemble boîtier supérieur, destiné à être raccordé à une source de pression de fluide comportant un mécanisme servant à régler une sortie pneumatique par le biais d'un signal d'entrée électrique. L'ensemble boîtier inférieur comprend un boîtier inférieur conçu pour recevoir une buse d'alimentation qui est en communication fluidique avec un orifice d'alimentation et en communication fluidique intermittente avec un orifice de sortie du boîtier inférieur par l'intermédiaire d'un passage de fluide interne. Le boîtier inférieur comprend en outre une buse d'évacuation en communication fluidique avec un orifice d'évacuation et en communication fluidique intermittente avec l'orifice de sortie du boîtier inférieur par l'intermédiaire du passage de fluide interne. L'ensemble boîtier supérieur comprend un boîtier supérieur conçu pour recevoir une bobine et un induit de sorte que le boîtier supérieur, la bobine et l'induit définissent un circuit électromagnétique de verrouillage qui fournit un contact alterné de l'induit avec la buse d'alimentation et la buse d'évacuation de l'ensemble boîtier inférieur.
