Описание

Устройство BC3250 – это контроллер продувки для парогенераторов. Открывая и закрывая клапан
продувки, контролирует TDS (общее содержание растворенных в растворе солей) в воде. Кроме того,
контролирует дренажный клапан, который удаляет с днища котла растворенные соли.
Функция оборудования – контроль электрической проводимости жидкости вместе с датчиком
проводимости, дренажным клапаном днища или дренажным клапаном конденсата.
Дренажный клапан днища регулируется таймером.
Контроллер может быть установлен на панели, на DIN-рейке или непосредственно на специальной
монтажной раме, питание 99/264 Vca.
Передняя панель снабжена графическим LCD дисплем и клавиатурой из 5 кнопок.
В случаях, когда датчик установлен непосредственно на котле, можно дополнительно использовать
фильтр с целью увеличения эффекта угасания. Данная система поможет избежать слишком частого
срабатывания клапана в случае турбулентности.
