Abstract

Perfeccionamientos en indicadores electrónicos de calcificación para calentadores de circulación o similar con elementos de circuito para la determinación de una variación de estado producida por la calcificación en aumento en el calentador de circulación, caracterizados porque el calentador de circulación se caldea por conductores con coeficientes de temperatura negativo, con una calefacción que tiene por lo menos, para la zona de su entrada de agua y para la zona de su salida de agua, en cada caso alimentaciones de corrientes separadas galvánicamente y disponiéndose un circuito con el que una variación de corriente relativa en estas alimentaciones de corriente, para las dos zonas de entradas y salida de agua, se utiliza como tensión de señal (diferencia de potencial A-B) para un dispositivo indicador.
