Title (EN) PROBE UNIT FOR INVESTIGATING FLUIDS
(FR) SONDE DE MESURE DE CARACTERISTIQUES D'UN FLUIDE
Abstract:
(EN) A sonde includes a plurality of discrete sensing electrodes (34, 36) of analog output projecting from a housing within which are accomodated a microprocessor (16) and an A/D converter (40) to digitise the output of the electrodes (34, 36). A stirrer is fully integrated into the housing and projects from the housing centrally with the electrodes around it. The stirrer motor (60) and the stirrer control (56) are integrated into the housing. The microprocessor (16) controls the stirrer control (56) e.g. as to on-off times, voltage and r.p.m. The sonde also has a readily attachable and detachable calibration cup with wells to enable each well to receive its own calibration solution and for all the electrodes to be calibrated simultaneously.
(FR) Sonde comprenant une pluralité d'électrodes détectrices discrètes et saillantes (34, 36) à sortie analogique disposées sur un boîtier renfermant un microprocesseur (16) et un convertisseur analogique/numérique (40) destiné à numériser les sorties des électrodes (34, 36). Un agitateur est entièrement intégré au boîtier et fait saillie à partir du centre de celui-ci de sorte que les électrodes l'entourent. Un moteur d'agitateur (60) et une commande d'agitateur (56) sont intégrés au boîtier. Le microprocesseur (16) commande les fonctions marche/arrêt, tension et vitesse de rotation de la commande d'agitateur (56). La sonde possède également un dispositif amovible d'étalonnage doté de cuvettes dont chacune peut recevoir une solution d'étalonnage différente de sorte que l'on puisse étalonner toutes les électrodes simultanément.
