Abstract

Un complesso di percezione comprende un elemento termoconduttore a forma di barra orientato radialmente rispetto ad una conduttura per fluido e due o più termocoppie installate sull'elemento termoconduttore. Una termocoppia è disposta più vicino alla conduttura dell'altra termocoppia. Dei segnali che dipendono dalla temperatura ottenuti dalle termocoppie vengono trasmessi ad adatte apparecchiature elettroniche di valutazione. L'apparecchiatura elettronica di valutazione determina una differenza di temperatura tra le due termocoppie basandosi sui segnali di termocoppia. La differenza di temperatura viene quindi confrontata con valori noti o prefissati per determinare lo stato di circolazione del fluido nella conduttura.
