Beschreibung
Zusammenfassung:	FIELD: measurement technology, specifically measurement of level of liquid in nuclear reactor vessel. SUBSTANCE: body of device is manufactured jointly with conductor, heater and two temperature-sensitive element in the form of one cable with mineral insulation. Heater id made from nichrome. Device also incorporates unit for adjustment of filament current and unit for correction of sluggishness of signal proportional to conductor resistance. Device makes it possible to indicate filling of vessel to the brim, to take into account corrections for temperature, liquid pressure and its rate, to make corrections for sluggishness of signal. EFFECT: enhanced operational reliability of device. 1 cl, 3 dwgi
