Abstract

Inventia se refera la un indicator termic si la nivel al topiturii pentru instalatii de crescut monocristale din substante ce prezinta o buna electroconductibilitate, în stare topita lucrand în vid sau gaz inert care se bazeaza pe dependenta între temperatura, respectiv nivel si variatia curentului unei diode în care anodul este reprezentat de topitura, iar catodul este realizat de un filament, electrozii fiind polarizati de o sursa stabilizata de tensiune cu care este înseriat un ampermetru, filamentul fiind încalzit suplimentar, în cazul masurarii nivelului de o sursa de curent constant masurat cu un ampermetru.
