مؤشر مستوى الالتفاف
الوصف
مؤشر مستوى التجاوز طراز BNA يتكوّن من حجرة تجاوز يتم تثبيتها على جانب الخزان كوعاء تواصلي عبر ما لا يقل عن 2 من وصلات العملية (وصلة شفة، اقتران ملولب أو قطعة لحام قصيرة). ومن خلال هذا النوع من الترتيب، يتوافق مستوى السائل في حجرة التجاوز مع مستوى السائل في الوعاء. يقوم العائم المزود بنظام مغناطيسي دائم مدمج، والذي يتم تركيبه داخل حجرة التجاوز، بنقل مستوى السائل، دون تلامس، إلى شاشة العرض المغناطيسية المثبتة على خارج حجرة التجاوز. وفي هذه الشاشة يتم تركيب، على فواصل 10 mm، بكرات بلاستيكية ثنائية اللون أو صفائح من الفولاذ المقاوم للصدأ مزودة بمغناطيسات شريطية.

مؤشر مستوى التجاوز، طراز BNA مع حساس مستوى ومفتاح مغناطيسي
من خلال المجال المغناطيسي للنظام المغناطيسي الدائم في العائم، يتم تدوير عناصر العرض، عبر جدار حجرة التجاوز، بمقدار 180°. بالنسبة لارتفاع المستوى من الأبيض إلى الأحمر؛ وبالنسبة لانخفاض المستوى من الأحمر إلى الأبيض. وبذلك يعرض مؤشر مستوى التجاوز بوضوح مستوى
وعاء دون جهد إمداد.

الأسئلة والأجوبة
ما هو مبدأ عمل مؤشر مستوى BNA؟
يعتمد على عائم مزود بنظام مغناطيسي دائم داخل حجرة التجاوز المتصلة جانبيًا بالوعاء، حيث ينقل المستوى دون تلامس عبر جدار الحجرة إلى شاشة عرض مغناطيسية تدور بمقدار 180°.
هل يحتاج المؤشر إلى مصدر تغذية؟
لا، يوفر عرضًا مستمرًا للمستوى دون جهد إمداد، ويمكن تركيب حساسات مستوى ومفاتيح مغناطيسية كخيار عند الحاجة إلى إشارات كهربائية.
ما هو مدى القياس؟
من 0,15 m إلى 6,0 m.
ما هي حدود درجة الحرارة والضغط في التشغيل؟
درجة حرارة التشغيل T = -196 … +450 °C، وضغط التشغيل P = تفريغ حتى 400 bar، بشرط كثافة حدية ρ ≥ 340 kg/m³.
ما هي وصلات العملية المتاحة؟
شفة EN 1092-1 (DN 10…100، PN 6…100)، شفة ANSI B16.5 (1/2"…4"، class 150…900)، قطعة لحام 1/2"…1"، ووصلات ملولبة G1/2…1 أو 1/2…1 NPT.
ما هي المواد المتاحة للأجزاء الملامسة للوسط؟
PP، PVDF، طلاء E-CTFE أو PTFE، الفولاذ المقاوم للصدأ 1.4571 (316Ti) و1.4401/1.4404 (316/316L) و6Mo 1.4547 (UNS S31254)، التيتانيوم 3.7035، وHastelloy C276 (2.4819).
هل تتوفر نسخ مقاومة للانفجار؟
نعم، بشهادات ATEX وIECEx لمناطق الغاز Zone 0/1 وZone 2 ومناطق الغبار، مثل II 1/2G Ex h IIC T6…T1 Ga/Gb وII -/2D Ex h IIIC T68…T360°C -/Db.
لماذا يُختار طراز BNA بدلًا من مؤشرات المستوى الأخرى؟
لأنه يعمل دون جهد إمداد، ويقاوم الوسائط العدوانية والقابلة للاشتعال والسامة والساخنة والملوثة بفضل المواد المتاحة، ويقبل تركيب حساسات ومفاتيح مغناطيسية إضافية.
