Abstract

SENSOR TERMOELECTRICO DE CORRIENTE EFICAZ VERDADERA. MIDE EL VALOR EFICAZ VERDADERO DE UNA CORRIENTE MEDIANTE LA COMPARACION DEL EFECTO TERMICO PRODUCIDO POR ESTA Y EL PRODUCIDO POR UNA CORRIENTE DE COMPARACION CONOCIDA, SOBRE DOS RESISTENCIAS CALEFACTORES, UNA DE MEDIDA (5) Y LA OTRA DE COMPARACION (6), MEDIANTE PARES TERMOELECTRICOS EN SERIE (1), DE FORMA QUE CADA PAR CONTIGUO ES CALENTADO POR EL FLUJO TERMICO PROCEDENTE DE CADA UNO DE LOS CALEFACTORES --EL DE MEDIDA (5) Y EL DE COMPARACION (6)-- GENERANDOSE UNA FUERZA ELECTROMOTRIZ QUE AMPLIFICADA Y TRATADA POR UN SUBSISTEMA ELECTRONICO, ESTABLECE UNA RETROALIMENTACION NEGATIVA QUE AJUSTA AUTOMATICAMENTE EL VALOR DE LA CORRIENTE DE COMPARACION QUE ANULA LA CITADA FUERZA ELECTROMOTRIZ, ESTABLECIENDOSE LA IGUALDAD ENTRE EL VALOR DE LA CORRIENTE DE COMPARACION --CONOCIDO-- Y EL VALOR EFICAZ DE LA CORRIENTE A MEDIR, PERMITIENDO LOS CALCULOS AUTOMATICOS DE CONSUMO ELECTRICO Y SU TRANSMISION MEDIANTE UNA INTERFACE PARA APLICACIONES TELEMATICAS.
