Abstract
Avisador de incendios por ionización, provisto de una cámara de ionización con por lo menos un orificio de entrada para el aire circundante, dos electrodos instalados en la cámara de ionización y conectados a una tensión eléctrica, y por lo menos una fuente radiactiva que produce una corriente de ionización entre los electrodos, caracterizado por el hecho de que por lo menos uno de los electrodos posea en su lado vuelto hacia otro electrodo un hoyo y porque la profundidad del hoyo y la distancia mínima entre los electrodos estén calculados de tal modo que se produzca en la zona entre los electrodos una corriente al menos parcialmente turbulenta cuando las velocidades del aire circundante sean como mínimo del orden de la velocidad de desplazamiento de los iones entre los electrodos y una corriente prácticamente laminar en el caso de velocidades inferiores.
