ITALIANO: Il piu usato eliofanografo e quello di Campbell-Stokes, ma questo strumento non consente l'acquisizione automatica ed e estremamente incerto per livelli di radiazione compresi fra 100-200 Wm-2. Presentiamo uno strumento nel quale la soglia per l'eliofania minima e rigorosamente stabilita e che fornisce in uscita, oltre a questa grandezza, tre segnali analogici corrispondenti alla radiazione diretta, diffusa e globale, utilizzando due sole fotocellule.

However, it cannot be used for automatic data acquisitions and the threshold level is not well defined. This paper describes an instrument in which the threshold for minimum sunshine is strictly established. The instrument not only gives the parameter but three other analogical signals: direct, diffuse and global radiation. All of this as been done with only two silicon cells.
