Abstract

Metodo per migliorare la precisione dei rivelatori a impedenza impiegati nelle radiosonde, consistente nel misurare la temperatura del (i) rivelatore (i) (30 e/o 10) per mezzo di una termocoppia (20), nella quale la giunzione (23) di un ramo dei suoi termoelementi (21, 22) è posta in collegamento co1, o nella prossimità del rivelatore che si deve misurare. Nella termocoppia (20), la giunzione (24) dell'altro ramo è posta nell'atmosfera (SA) che circonda il rivelatore. Mediante la termocoppia (20), viene rivelata la differenza (T1 -Toe) fra la temperatura (T1) che prevale in relazione al rivelatore e la temperatura (To) esistente nell'atmosfera (SA) circostante. Il segnale (fout) in uscita dall'accoppiamento di misura della radiosonda viene influenzato mediante un segnale elettrico (U(t)) che rappresenta la differenza (T1-To) di temperatura, e che contiene i dati concernenti 1a(e) quantità meteorologiche misurate mediante il rivelatore (30) o i rivelatori (10, 30).
