Оборудование для профессионалов
Оборудование для профессионаловДиапазон работ, осуществляемых газоанализаторами серии VARIOTEC®4XX, позволяет выполнять большой спектр задач в газораспределительных сетях с максимальной эффективностью.
В серии VARIOTEC®4XX используются те же аксессуары и зонды, которые применялись в прошлых поколениях приборов SEWERIN, поэтому при наличии старых, Вам не придется покупать новые.
В приборах с аббревиатурой 480 EX и 460 EX могут быть использован (опция), этан-детектор, который позволяет различать природный газ и болотный. Теперь будет меньше ложных показаний из-за природы газа.
Все модификации, кроме VARIOTEC®400 EX, могут быть оснащены сенсорами на кислород и оксид углерода (опция)
Особенности
Функционал
• Уникальный и простой в использовании прибор, посредством трех функциональных клавиш и джойстика, интуитивное меню
• Большой матричный дисплей с подсветкой показывает все уровни газа
• Быстрая зарядка в течение 4 часов – позволяет увеличить рабочее время использования прибора
• Питание от 4 аккумуляторных батарей типа АА (одноразовые или перезаряжаемые)
• Все данные могут быть перенесены на ПК через USB-порт
• Ручка для переноски имеет двойное назначение: как для удобного расположения прибора в работе при креплении ремнями, так и для установки его на столе.
Эффективность
• Простота: контекстное меню и его структура позволяют новому пользователю без особой подготовки быстро
приступить к работе
• Нет необходимости в сложной перенастройке прибора,
даже если он длительно время не использовался.
• Быстрая самоокупаемость для оператора: экономия средств на обслуживании, сокращение времени на бумажные отчеты.
Используемые сенсоры
• Быстрый и высокочувствительный полупроводниковый сенсор используется для определения очень низких концентраций газа в диапазоне измерения частей на миллион (ppm)
• Интегрированный газовый хроматограф для определения компонентов газовой пробы: метан, этан, пропан.
Разрешения (сертификаты)
• Взрывозащита:
TÜV 07 ATEX 553353 X II2G Ex d e ib IIB T4 Gb, IIC при использовании кожаной сумки-переноски
• Функция измерения:
BVS 09 ATEX G 001 X N1, PFG 08 G 002 X N1 (функция измерения доступна только для VARIOTEC®480 EX и VARIOTEC®450 EX )
Описание модели по типам применения
Выбор прибора
X = стандарт O = опция
Приложение: Наземный контроль
Измерение низких концентраций газа наповерхности земли и над газовыми трубами
Пример: Инспекция подземного газопровода
Приложение: Внутридомовой контроль
Измерение низких концентраций газа в зданиях и их локализация
Пример: Обнаружение утечек в доступных местах
Приложение: Мониторинг воздуха рабочей зоны (Предупреждение взрывозащиты и предупреждение токсичных газов)
Мониторинг и защита воздуха рабочей зоны, защита персонала вовремя работы вблизи газопроводов или на объектах, где возможен риск образования взрывоопасной концентрации газа.
Пример: При проведении работ на газораспределительных станциях, биогазовых установках, в работе аварийных бригад при реакции на запах газа.
Приложение: Закрытое пространство
Измерение концентрации газа, где существует потенциальная опасность образования взрыва
Пример: Шахты (телекоммуникационные, канализационные, электрощитовые)
Приложение: Измерения в шурфах
Измерение концентрации газа и его распространения согласно классификатору, локализация предположительного места утечки газа.
Пример: Локализация места поиска утечки
Приложение: Измерение концентрации газа
Измерение концентрации газа / подтверждение отсутствия природного газа или кислорода в трубе
Пример: Ввод / Вывод из эксплуатации газопроводов
Приложение: Анализ на этан
Определение метана, этана и пропана в газовоздушной пробе
Пример: При показаниях утечки газа нужно определить характер газа, чтобы различить природный и болотный газ.
Анализ на этан – Природный газ или болотный (свалочный) газ?
Газоанализаторы-течеискатели серии VARIOTEC® 4×0 помогают оператору найти и локализовать места утечки газа в подземных газопроводах.
Перед тем, как приступать к дорогостоящему вскрытию грунта и инспекции газопровода, убедитесь, что вы обнаружили утечку природного газа из трубы, и что он не болотный газ или газ другого происхождения.
В качестве опции устанавливается этан-детектор, который просто и быстро позволяет определить отличия между природным и болотным (свалочным) газом.
Не требуется каких либо дополнительных принадлежностей или специального обучения, чтобы работать в этом режиме.
Пользовательское меню сопровождается подсказками и оператору не составляет труда провести измерения. Все показания сохраняются в памяти прибора и могут быть перенесены на ПК.
Измерить содержание кислорода – Как более точно определить место утечки?
В ситуации, когда утечка газа распространилась по большой поверхности грунта в течение длительного периода времени, бывает сложно определить точное место утечки. Дополнительно установленный сенсор на кислород позволяет одновременно контролировать концентрацию кислорода и природного газа. В точке, где концентрация по метану будет наивысшей и одновременно концентрация по кислороду будет наименьшей, будет находиться наиболее
вероятное место утечки.
