الوصف

إن الطراز DPT-20، مع إشارات الخرج 4 ... 20 mA أو 4 ... 20 mA HART ® أو FOUNDATION™ Fieldbus أو PROFIBUS ® PA، والمُدمج مع نوع حماية الاشتعال لسلامة الجوهرية أو الحماية من الانفجار بسبب اللهب (flameproof)، مناسب بشكل مثالي للتطبيق في الأنظمة المناسبة. كما أن تطوير المُرسِل وفقًا لمتطلبات SIL (Safety Integrated Level) IEC 61508 يجعل منه مناسبًا أيضًا للمواقع/المصانع التي تتطلب متطلبات سلامة خاصة.

المزايا

  • دقة قياس عالية
  • مدى قياس قابل للمعايرة بحرية
  • مطوَّر وفقاً لمتطلبات SIL 2
  • سبعة أشكال مختلفة للهيكل
  • التهيئة عبر DTM (Device Type Manager) وفقًا لمفهوم FDT (Field Device Tool) (مثل PACTware™)

الأسئلة والأجوبة

ما هو مدى القياس لمرسل DPT-20؟

هل يمكن استخدام هذا المرسل في مناطق خطرة؟

نعم، فهو متوفر بحماية اشتعال بالسلامة الجوهرية وبحماية من الانفجار (flameproof enclosure)، مع شهادات CE وNACE.

ما هي إشارات الخرج المتاحة؟

تشمل 4 ... 20 mA، و4 ... 20 mA HART، وFOUNDATION™ Fieldbus، وPROFIBUS® PA.

ما نوع توصيل العملية المتاح؟

التوصيلات المتاحة هي ½ NPT و¼ NPT وG 1/2 وM20x1.5.

ما المواد التي تلامس المائع؟

الأجزاء الملامسة للمائع متوفرة من 316L أو Hastelloy، ومواد الإحكام تشمل FKM وEPDM وFPM وNBR.

ما حدود درجة الحرارة المسموح بها؟

درجة حرارة البيئة المحيطة ودرجة حرارة المائع كلتيهما من -40 °C إلى +85 °C.

هل يناسب المصانع ذات متطلبات السلامة الوظيفية؟

نعم، فقد طُوِّر المرسل وفقًا لمتطلبات SIL 2 وفق المعيار IEC 61508، مما يجعله مناسبًا للمواقع التي تتطلب متطلبات سلامة خاصة.

كيف تتم تهيئة الجهاز؟

تتم التهيئة عبر DTM (Device Type Manager) وفقًا لمفهوم FDT، باستخدام برامج مثل PACTware™.
