Title (EN) CURRENT TO PRESSURE CONVERTER APPARATUS
(FR) DISPOSITIF CONVERTISSEUR DE COULANT EN PRESSION
Abstract: front page image
(EN)A current controlled pressure regulating apparatus for operating pneumatically operated elements such as valves in process control systems and the like. A process variable provides a DC electrical control signal via transmitter (101) to control a fluid amplifier (110-30'). A feedback signal (23'-25') from the fluid amplifier (30') is electrically combined with control signal.
(FR)Dispositif de regulation de la pression commandee par le courant destine a l'actionnement d'elements commandes pneumatiquement tels que des soupapes dans les systemes de commande d'operation et similaires. Une variable de l'operation fournit un signal electrique de commande a courant continu au travers d'un dispositif de transmission (101) pour commander un amplificateur de fluide (110-30'). Un signal de reaction (23'-25') provenant de l'amplificateur de fluide (30') est combine electriquement avec le signal de commande.
