Abstract
(DE) Die vorliegende Erfindung betrifft eine automatisierbare Mess-, Reinigungs- und/oder Kalibriereinrichtung für Elektroden zur Messung von pH-Werten oder Redoxpotentialen, insbesondere in der Prozesstechnik, mit einem Messumformer (8), der einen programmierbaren Prozessrechner zur Ausführung von Prozessschritten aufweist, und mit einer Steuereinheit (10), die mehrere Stellglieder (44) und/oder Signaleingänge (42) und/oder Signalausgänge (40) aufweist. Zur besseren Programmierbarkeit der Einrichtung ist eine funktionale Trennung zwischen dem Messumformer (8) und der Steuereinheit (10) vorgesehen, wobei ein Datenaustausch über eine bidirektionale Kommunikationsverbindung (13) erfolgt. Darüber hinaus wird ein Verfahren zum Betrieb dieser automatisierbaren Mess-,Reinigungs- und/oder Kalibriereinrichtung für Elektroden zur Messung von pH-Werten oder Redoxpotentialen beschrieben.
(EN) The invention relates to a measuring, cleaning and/or calibration device for electrodes for the measurement of pH values or redox potentials which may be automated, in particular in process technology, with a measuring transducer (8), comprising a programmable process computer for carrying out process steps and a controller (10),comprising several actuators (44) and/or signal inputs (42) and/or signal outputs (40). A functional separation of the measuring transducer (8) and the controller (10) is provided for an improved programmability of the device, whereby an exchange of data occurs by means of a bi-directional communication connection (13). The invention further relates to a method for the operation of said measuring, cleaning and/or calibration device, for electrodes for the measurement of pH values or redox potentials, which may be automated.
(FR) La présente invention concerne un système automatisable de mesure, de nettoyage et/ou d'étalonnage destiné à des électrodes de mesure de pH ou de potentiels redox, en particulier dans le domaine des techniques de commande de processus. Ce système comprend un convertisseur de mesure (8), équipé d'un ordinateur de commande de processus programmable servant à exécuter des étapes de processus, ainsi qu'une unité de commande (10) pourvue de plusieurs éléments d'actionnement (44) et/ou d'entrées de signaux (42) et/ou de sorties de signaux (40). Selon l'invention, pour accroître la programmabilité du système, le convertisseur de mesure (8) et l'unité de commande (10) sont fonctionnellement séparés, un échange de données étant établi par l'intermédiaire d'une liaison de communication bidirectionnelle (13). L'invention concerne en outre un procédé permettant de faire fonctionner un tel système.
