Abstract

Устройството намира приложение за определяне нивото на топлоносителя в реактор с цел повишаване информационната точност на измерването. То има продълговат корпус (1), в който надлъжно са разпределенинагрявани термоелектрически измерватели (2, 3) и между техни спойки (12, 13) е монтиран ненагряван спомагателен термоелектрически измервател (4) от кабелен тип, с което се създава възможност за непрекъснато измерване на температурата на топлоносителя. В друг вариант на устройството в продълговат корпус (1) са разпределени надлъжно диференциални термоелектрически измерватели (19, 20) от кабелен тип, между краищата на които е разположен ненагряван спомагателен термоелектрически измервател (21). Система (6) за електронагряване на спойките на термоелектрическите измерватели е изпълнена като дискретни нагревателни елементи (16, 17), свързани последователно чрез проводници (15) от кабелен тип. Обвивката (9) на термоелектрическите измерватели (2, 3, 4, 5) в зоните на монтаж на техните спойки и обвивките (26) на нагревателните елементи (16, 17) са свързани към вътрешната повърхност на корпуса (1) чрез запоени връзки (7).
