Title (EN) AUTOMATIC VALVE CHARACTERIZATION OF DIGITAL VALVE POSITIONERS
(FR) CARACTERISATION DE SOUPAPE AUTOMATIQUE D'UN POSITIONNEUR DE SOUPAPE NUMERIQUE
Abstract: front page image
(EN)A digital valve positioner is controlled to automatically characterize a valve to provide a linear relationship between the valve control signal and the amount of flow.
(FR)L'invention concerne un positionneur de soupape numérique destiné à commander de manière automatique une soupape, ceci permettant de créer une relation linéaire entre le signal de commande de la soupape et la quantité de flux.
