ADJUSTABLE HEATING DEVICE FOR SMALL MASSES, ESPECIALLY OF EXPANDABLE SUBSTANCE OF THERMAL CONTROL DEVICES
Реферат: DISPOSITIF CHAUFFANT REGLABLE POUR PETITES MASSES, NOTAMMENT DE SUBSTANCE DILATABLE, DE DISPOSITIFS DE COMMANDE THERMIQUES, COMPORTANT UN ELEMENT CHAUFFANT ET UN CAPTEUR DE TEMPERATURE, DISPOSES DANS LADITE MASSE, ET UN ENSEMBLE DE REGULATION QUI REGLE LE COURANT DE CHAUFFAGE AU MOINS EN FONCTION DU SIGNAL DE TEMPERATURE DU CAPTEUR DE TEMPERATURE. L'ELEMENT CHAUFFANT DE CE DISPOSITIF EST CONSTITUE PAR UN TRANSISTOR 25, DONT LES PERTES DE PUISSANCE ASSURENT LE CHAUFFAGE DESIRE ET LA CHUTE DE TENSION LE LONG DE L'ESPACE BASE-EMETTEUR DE CE TRANSISTOR SERT DE SIGNAL DE TEMPERATURE. APPLICATION: DISPOSITIFS DE COMMANDE THERMIQUE. ADJUSTABLE HEATING DEVICE FOR SMALL MASSES, ESPECIALLY OF EXPANDABLE SUBSTANCE, THERMAL CONTROL DEVICES, INCLUDING A HEATING ELEMENT AND A TEMPERATURE SENSOR, PROVIDED IN THE SAID MASS, AND A REGULATION ASSEMBLY WHICH ADJUSTS THE HEATING CURRENT AT MINUS TEMPERATURE SENSOR TEMPERATURE. THE HEATING ELEMENT OF THIS DEVICE IS CONSTITUTED BY A TRANSISTOR 25, WHOSE POWER LOSSES ENSURE THE DESIRED HEATING AND THE VOLTAGE DROP ALONG THE BASE-EMITTER SPACE OF THIS TRANSISTOR SERVES AS A TEMPERATURE SIGNAL. APPLICATION: THERMAL CONTROL DEVICES.
