Abstract

La présente invention concerne des dispositifs et des procédés de commande d'une pression de fluide dans laquelle la température d'un volume de fluide de travail est régulée afin de fournir une pression de référence. Dans des modes de réalisation, le dispositif comprend un boîtier, un réservoir de fluide et un dispositif de commande, le boîtier comprenant : un passage de fluide pour un fluide de traitement, dont la pression doit être commandée ; un volume de référence pour fournir une pression de référence ; et une membrane ayant une surface de travail en contact avec le passage de fluide et une surface de référence en contact avec le volume de référence, et dans lequel : le réservoir de fluide est en communication avec le volume de référence et contient un volume de fluide de travail ; et le dispositif de commande est configuré pour réguler la température du fluide de travail afin de commander la pression de référence.
