مفتاح ضغط بغشاء (Diaphragm) بعلبة مقاومة للهب Ex d
الوصف
تم تطوير مفاتيح الضغط الميكانيكية عالية الجودة هذه خصيصًا لتطبيقات تتطلب السلامة بدرجة حرجة. تتمثل الميزة الكبيرة لمفاتيح الضغط الميكانيكية في أنه لا يلزم وجود جهد إمداد لعملية التبديل.
في الإنتاج، يتم تتبّع المفاتيح بواسطة برنامج ضمان الجودة في كل خطوة، ثم يتم اختبارها بنسبة 100 %. يمكن للهيكل المتين للمفتاح المصنوع من سبائك الألومنيوم أن يتحمل ظروف التشغيل القاسية والمسببة للتآكل في صناعة العمليات، ضمن مجالات عمل تصل إلى 600 bar. يتم تركيب مفتاح الضغط مع 1 أو 2 ميكروسويتش، مما يتيح تبديل حمل كهربائي حتى AC 250 V، 20 A مباشرةً.
بالنسبة لقدرات القدرة الأقل للتبديل، مثل تطبيقات PLC، تتوفر ميكروسويتشات مملوءة بغاز الأرجون مع نقاط تلامس مطلية بالذهب.

ما هي وسائط التشغيل المناسبة لهذا المفتاح؟
الوسائط الغازية والسائلة، العدوانية وعالية اللزوجة أو الملوثة، وأجزاء ملامسة من Stainless steel 316/316L أو Monel أو Hastelloy C276 أو PTFE حسب الاختيار.
ما هي درجات الحرارة المسموح بها؟
يعمل المفتاح عند درجة حرارة محيط ووسط تتراوح بين -60 … +85 °C.
ما هو اتصال العملية المتاح؟
خيارات تشمل 1/4 NPT و1/2 NPT وG 1/2 B وM20x1.5، إضافة إلى فلنجات ASME B16.5 Class 150/300/600 وEN 1092-1 PN 10/40.
كم عدد نقاط التبديل وما قدرتها؟
يتوفر 1 أو 2 نقطة تبديل مستقلة (SPDT/DPDT) بقدرة تبديل تصل إلى AC 250 V، 20 A مباشرةً، مع خيار ميكروسويتشات مملوءة بالأرجون بنقاط تلامس مطلية بالذهب لتطبيقات PLC ذات القدرة الأقل.
ما الذي يميز طراز MA عن باقي طرازات العائلة؟
طراز MA مصنف II 1/2 GD مثل MAB وMAG، بينما طراز MAH مصنف II 2 GD؛ وجميعها تعمل بغلاف مقاوم للهب Ex d للتطبيقات الحرجة من ناحية السلامة. ---
