مقياس ضغط تفاضلي مع ملامسات/تلامسات تبديل
الوصف
حيثما يلزم بيان ضغط العملية محليًا وفي الوقت نفسه يلزم تبديل الدوائر، يُستخدم مقياس التبديل switchGAUGE لطراز DPGS43HP.1x0.
تقوم جهات التلامس الخاصة بالمفتاح (جهات تلامس إنذار كهربائية) بفتح أو إغلاق الدوائر اعتمادًا على وضع المؤشر الخاص بأجهزة القياس التي تعرض القياس. يمكن ضبط جهات التلامس الخاصة بالمفتاح على كامل مدى نطاق السلم (انظر DIN 16085)، ويتم تركيبها بشكل أساسي أسفل وجه الساعة، على الرغم من أنها قد تكون أيضًا مركبة جزئيًا فوق وجه الساعة. يتحرك مؤشر الجهاز (مؤشر القيمة الفعلية) بحرية عبر كامل مدى السلم، دون أن يتأثر بإعدادات الضبط.
يمكن ضبط المؤشر المُعدَّل باستخدام مفتاح ضبط قابل للإزالة عبر النافذة.
المزايا
- ضغط تشغيل مرتفع (ضغط ساكن) وأمان تحمّل زائد مرتفع، قابل للاختيار حتى 40 أو 100 أو 250 أو 400 أو 650 بار [580 أو 1,450 أو 3,625 أو 5,800 أو 9,425 psi]
- تخميد هيدروليكي للحماية من تغيرات الضغط السريعة
- أجهزة بنقاط اتصال حثية للاستخدام في المناطق الخطرة
- أجهزة ذات ملامس تبديل لتطبيقات PLC
- رمز QR على القرص يوفر رابطاً إلى معلومات خاصة بالجهاز
الأسئلة والأجوبة
ما هو نطاق القياس المتاح لهذا الجهاز؟
يتوفر الجهاز بنطاقات واسعة تبدأ من 0 … 60 mbar وصولًا إلى 0 … 40 bar، بالإضافة إلى نطاقات بالوحدات kPa وpsi وinHg، وتشمل أيضًا نطاقات فراغية ومركبة مثل -1 … 15 bar.
ما هي دقة القياس؟
فئة الدقة 1.6 وفق المعيار EN 837-3.
ما خيارات وصلة العملية؟
شفة بوصلة ضغط تفاضلي، أو خيوط ذكر 2 x G ½ B أو 2 x ½ NPT، أو خيوط أنثى G ½، بين خيارات أخرى مطابقة.
هل يمكن استخدامه في المناطق الخطرة؟
نعم، تتوفر نسخ بجهات تلامس حثية معتمدة وفق ATEX وIECEx بتصنيف II 2G Ex ia IIC T6/T5/T4 Gb وII 2D Ex ia IIIB T135°C Db.
ما المواد المتاحة للأجزاء المبللة بالوسط؟
Stainless steel 316L، Hastelloy C276، Monel 2.4375، Monel 2.4360، وStainless steel 316L / NiCr alloy (Inconel)، مما يجعله مناسبًا للبيئات العدوانية.
ما حدود درجات الحرارة للتشغيل؟
درجة حرارة الوسط من -20 … +200 °C، ودرجة الحرارة المحيطة من -20 … +60 °C.
ما الذي يميز هذا الطراز عن مقاييس الضغط التفاضلي الأخرى؟
يجمع هذا الطراز بين العرض التناظري المحلي دون قدرة مساعدة وجهات تلامس تبديل (حتى 3 جهات بوظيفة Change-over)، مع أمان عالٍ ضد زيادة التحميل حتى 650 بار وحماية هيدروليكية ضد التغيرات السريعة في الضغط. ---
