Описание

Поплавок с постоянным магнитом надёжно перемещается вместе с уровнем жидкости по направляющей трубе. Внутри направляющей трубы установлен геркон (контакт для инертного газа), который подаётся под напряжение через немагнитные стенки поплавка и направляющей трубы при приближении магнита поплавка. За счёт применения магнита и герконового контакта операция переключения выполняется бесконтактно, не подвержена износу и не требует электропитания. Контакты являются потенциально-развязанными. Также доступны поплавковые выключатели с несколькими точками переключения.

Функции переключения всегда относятся к повышающемуся уровню жидкости: нормально разомкнутый, нормально замкнутый или переключающий контакт.

За счёт применения поплавка максимум на 2 точки переключения можно обеспечить бистабильное поведение переключателя, то есть состояние переключения сохраняется также тогда, когда уровень заполнения продолжает подниматься выше или опускаться ниже точки переключения.

Поплавковый выключатель прост в монтаже и не требует технического обслуживания, поэтому затраты на монтаж, пусконаладку и эксплуатацию невысоки.

Вопросы и ответы

Какой диапазон уровней измеряет поплавковый выключатель FLS?

От 0 до 6000 мм в зависимости от длины направляющей трубы.

В каком диапазоне температур и давлений работает прибор?

Рабочая температура от -50 до +350 °C, рабочее давление — от вакуума до 40 бар; минимальная плотность среды ρ ≥ 300 кг/м³.

Какие присоединения к процессу доступны?

Резьбовые G 1 1/2" и G 2", фланцевые по DIN DN 50 … DN 200 и ANSI 2" … 8".

Для каких сред подходит выключатель?

Практически для всех жидких сред с плотностью не ниже 300 кг/м³; материалы смачиваемых частей включают нержавеющие стали 1.4571 (316Ti), 1.4404 (316L), 1.4435 (316L), пластик (PP, PA), латунь, Titanium и Hastelloy.

Какая степень защиты корпуса?

IP66/IP68; корпус подключения выполнен из алюминия размером 64 x 58 x 34 мм с одним контактом.

Есть ли взрывозащищённые исполнения?

Да: версии Ex i (Ex ia IIC T6 … T1 Ga/Gb) и Ex d (Ex d IIC T6 Gb) для газовых и пылевых сред.

Чем FLS-S отличается от FLS-P?

Модель FLS-S выполнена из нержавеющей стали с монтажной резьбой, модель FLS-P — из пластика с фланцевым соединением; обе работают по одному магнито-герконовому принципу.

Какой тип выходного сигнала обеспечивает выключатель?

Нормально разомкнутый (NO), нормально замкнутый (NC) или переключающий контакт (SPDT); питание — безопасное сверхнизкое напряжение, контакты потенциально развязаны.
