Abstract

Aparato del tipo utilizado para detectar la presencia de pirolisatos en un soporte gaseoso, estando dicho soporte gaseoso constituido por una muestra de gas de refrigeración procedente de una máquina dinamoeléctrica enfriada por un gas, de la cual algunas partes están revestidas con materiales elegidos que se descomponen a una temperatura elevada produciendo pirolisatos que indican un sobrecalentamiento localizado de las piezas de la máquina dinamoeléctrica; incluyendo dicho aparato un recinto externo que contiene una sección de mezclado e ionización de gas y una sección de detección, recibiendo dicha sección de detección dicha muestras de gas ionizado procedente de dicha sección de mezclado e ionización de gas, incluyendo dicha sección de detección unos electrodos separados a los cuales se aplica una tensión de modo que entre ellos circule una corriente producida por el gas ionizado con el fin de obtener una señal variable cuya amplitud es proporcional a la circulación de la corriente.
