Abstract

DETECTEUR UNIPOLAIRE CAPABLE D'INDIQUER LA PRESENCE D'UNE TENSION INDUSTRIELLE ALTERNATIVE PAR L'EMISSION D'UN SIGNAL LUMINEUX PRODUIT PAR UN TUBE A DECHARGE COMPORTANT DEUX ELECTRODES PRINCIPALES ET UNE ELECTRODE DE COMMANDE. L'ENERGIE DE LA DECHARGE LUMINEUSE EST FOURNIE PAR UN CONVERTISSEUR DE TENSION ALIMENTE PAR UNE SOURCE A BASSE TENSION TELLE QU'UNE BATTERIE. LE CONVERTISSEUR COMPREND ESSENTIELLEMENT UN GENERATEUR D'OSCILLATIONS DONT LE FONCTIONNEMENT EST COMMANDE PAR L'APPLICATION AU PALPEUR DE L'APPAREIL D'UNE TENSION ALTERNATIVE AU MOINS EGALE A UN SEUIL DETERMINE. UN CIRCUIT DE RELAXATION PRODUIT SUR L'ELECTRODE DE COMMANDE DU TUBE A DECHARGE DES IMPULSIONS PERIODIQUES DONT LA CADENCE EST INDEPENDANTE DE LA TENSION APPLIQUEE AU PALPEUR.SINGLE POLE DETECTOR CAPABLE OF INDICATING THE PRESENCE OF AN ALTERNATIVE INDUSTRIAL VOLTAGE BY THE EMISSION OF A LIGHT SIGNAL PRODUCED BY A DISCHARGE TUBE CONTAINING TWO MAIN ELECTRODES AND A CONTROL ELECTRODE. THE ENERGY FOR THE LUMINOUS DISCHARGE IS PROVIDED BY A VOLTAGE CONVERTER SUPPLIED BY A LOW VOLTAGE SOURCE SUCH AS A BATTERY. THE CONVERTER ESSENTIALLY INCLUDES AN OSCILLATION GENERATOR WHOSE OPERATION IS CONTROLLED BY APPLYING THE APPARATUS TO AN ALTERNATIVE VOLTAGE AT LEAST EQUAL TO A DETERMINED THRESHOLD. A RELAXATION CIRCUIT PRODUCED ON THE TUBE'S CONTROL ELECTRODE DISCHARGE PERIODIC PULSES THE RATE OF WHICH IS INDEPENDENT OF THE VOLTAGE APPLIED TO THE PROBE.
