Abstract

En pneumatisk kontroller for styring av en prosess reduserer med fordel fluidforbruk ved tilveiebringelse av en proporsjonaljustering av et tilbakekoplingssignal. Den pneumatiske kontroller omfatter et pneumatisk styringstrinn, en prosesstrykkdetektor og en tilbakekoplingsproporsjoneringsinnretning. Tilbakekoplingsproporsjoneringsinnretningen bruker en tilbakekoplingsutliggerkomponent til å tilveiebringe proporsjonaljusteringen av tilbakekoplingssignalet, hvilket reduserer fluidforbruket til den pneumatiske kontroller
