Title (EN) METHOD AND APPARATUS FOR DETERMINING THE THICKNESS OF A CHARGE WALL FORMED IN A CENTRIFUGAL BASKET
(FR) PROCEDE ET APPAREILLAGE POUR DETERMINER L"EPAISSEUR D"UNE CHARGE DE PAROI FORMEE DANS UN PANIER DE CENTRIFUGEUR
Abstract: front page image
(EN)A method for determining the thickness of a charge wall being formed against the side wall of a rotating centrifugal basket (12) by flow of charge material into the basket comprises the steps of establishing a capacitance across the charge space(s) of the basket and sensing any change of capacitance which results as the charge wall thickness is increased by the flow. An apparatus for determining the thickness of the charge wall formed against the side wall of the centrifugal basket (12) includes an electrically conductive plate (36), disposed in the basket inwardly of the charge space (S), and a source of voltage (38) for establishing an electric field between the plate and the side wall. A capacitance sensor (41) senses any change in the established capacitance resulting from the formation of a charge wall in the basket. The capacitance sensor (41) is connected to a logic network (74) which controls operation of a loading control gate (18).
(FR)Procede de determination de l"epaisseur d"une charge de paroi qui se forme contre la paroi laterale d"un panier rotatif de centrifugeur (12) par l"ecoulement d"un materiau de charge au travers du panier, comprenant les etapes de l"etablissement d"une capacitance a travers le(les)" espaces) de charge du panier et de distinguer tout changement de capacitance qui resulterait de l"epaisseur de la charge de paroi qui se forme par l"ecoulement. Un appareillage pour la determination de l"epaisseur de la charge de paroi formee contre la paroi laterale du panier de centrifugeur (12) comprend une plaque conductrice electriquement (36) disposee dans le panier interieurement de l"espace de charge (S), et une source de courant (38) pour l"etablissement d"un champ electrique (38) entre la plaque et la paroi laterale. Un appareil de mesure de capacitance (41) distingue tout changement de la capacitance resultant de la formation d"une charge de paroi dans le panier. L"appareil (41) est relie a un reseau logique (74) qui controle le taux de chargement.
