Система контроля диафрагмы с протоколом HART ®
Описание
Система контроля диафрагмы DMSU21SA обеспечивает надёжное измерение давления в процессах с чистым паром. Гигиеническое исполнение, включающее технологический преобразователь, мембранный разделитель и элемент контроля, предусматривает двойную диафрагму для защиты от загрязнения продукта, поскольку заполняющая система не может вытечь в случае разрыва диафрагмы, а сам разрыв регистрируется непосредственно. Благодаря наличию различных вариантов технологических присоединений систему можно интегрировать практически на всех предприятиях.
Система DMSU21SA работает при максимальных температурах среды от -10 до +150 °C [14 ... 266 °F] и температуре окружающей среды 10 ... 40 °C [50 ... 104 °F], а также доступна в исполнении для IECEx и ATEX.
Особенности
- Система с двойной мембраной предотвращает загрязнение процесса и окружающей среды
- Гигиенические технологические присоединения в различных исполнениях
- 2 варианта обработки сигнала контроля мембраны: непосредственно встроенный в измерительный преобразователь или отдельный
- Минимальные затраты на монтаж, в том числе при модернизации

| Switch contact status | → See 'Output signal' | |
| Variant 1 | With integrated signal processing, the switch contact of the monitoring element is moni- tored in the process transmitter and output via the HART protocol or as an error signal on the current loop. | |
| Variant 2 | Separate signal processing of the monitoring element requires an additional cable and monitoring of the switch contact on the customer side. | |
| Alarm signal condition | For the monitoring element to change the status of the switch contact, the specified set point must be reached for at least 1.5 seconds.This prevents shocks or vibrations from triggering the alarm signal unintentionally. | |
