Abstract
DISPOSITIVO PERCEPTOR PARA RECONOCER PRECIPITACIONES DE ESCARCHA. CARACTERIZADO PORQUE ENTRE UNA FUENTE DE CALOR (3) Y UN SENSOR DE TEMPERATURA (4), QUE ESTAN DISPUESTOS CON UNA SEPARACION ENTRE SI, EXISTE UNA UNION TERMICA (2) DE UN MATERIAL CUYA CONDUCTIVIDAD CALORIFICA ESPECIFICA ES DEL MISMO ORDEN DE MAGNITUD QUE LA CONDUCTIVIDAD CALORIFICA ESPECIFICA DE LA ESCARCHA; PORQUE LA FUENTE DE CALOR Y EL SENSOR DE TEMPERATURA ESTAN DISPUESTOS EN UNA CAJA COMUN; PORQUE DICHA CAJA REALIZA LA UNION CON UNA CONDUCTIVIDAD CALORIFICA ESPECIFICA, DEL ORDEN DE MAGNITUD DE LA CONDUCTIVIDAD CALORIFICA ESPECIFICA DE LA ESCARCHA. DE APLICACION EN INSTALACIONES DE REFRIGERACION, TALES COMO CONGELADORES O SIMILARES.
