ميزان الضغط
الوصف
ميزان ضغط تفاضلي (deadweight tester) لمعايرة أجهزة قياس فرق الضغط تحت ضغط ساكن، مع توليد ضغط مدمج. يعمل بالتطبيقات الهوائية والهيدروليكية حتى 1,600 بار، ويُستخدم كمعيار أولي في مصانع ومختبرات المعايرة، كما يصلح للاستخدام الميداني كنظام مستقل متكامل.
المزايا
- مدايا القياس (= الضغط الساكن + ضغط الفرق) حتى 400 bar [5,000 psi] هوائي، وحتى 1,600 bar [23,200 psi] هيدروليكي
- عدم اليقين الكلي للقياس حتى 0.008 % من فرق الضغط زائد 0.0001 % [1 ppm] من الضغط الساكن
- معايرة المصنع مشمولة كمعيار، قابلة للتتبع إلى المعايير الوطنية؛ مع إمكانية معايرة DKD/DAkkS كخيار
- ثبات طويل الأمد عالٍ مع فترة إعادة معايرة موصى بها كل خمس سنوات
- أوزان مصنوعة من الفولاذ المقاوم للصدأ والألومنيوم، يمكن تعديلها حسب الجاذبية المحلية
الأسئلة والأجوبة
ما هي مدى القياس المتاحة للطراز CPB5600DP؟
المدى الكلي = الضغط الساكن + فرق الضغط: حتى 400 bar [5,000 psi] للتطبيقات الهوائية وحتى 1,600 bar [23,200 psi] للتطبيقات الهيدروليكية، مع مدى تفاضلي يبدأ من 0.03 bar.
ما دقة الجهاز؟
عدم اليقين الكلي 0.008 % من قراءة فرق الضغط، بالإضافة إلى 0.0001 % [1 ppm] من قراءة الضغط الساكن.
ما الوسائط التي يعمل بها الجهاز؟
هواء ونيتروجين للتطبيقات الهوائية، وزيت هيدروليكي للتطبيقات الهيدروليكية.
هل يشمل الجهاز شهادة معايرة؟
نعم، تشمل معايرة مصنعية قابلة للتتبع إلى المعايير الوطنية كمعيار، ويمكن طلب معايرة DKD/DAkkS كخيار إضافي.
ما فترة إعادة المعايرة الموصى بها؟
بفضل الثبات طويل الأمد العالي، يوصى بإعادة المعايرة كل خمس سنوات فقط.
هل يمكن استخدامه خارج المختبر؟
نعم، فهو نظام مستقل متكامل بتوليد ضغط مدمج، مناسب أيضاً للاستخدام في الموقع، بوزن 45 kg وحماية IP54.
ما الذي يميز هذا الطراز عن موازين الضغط الأخرى؟
إنه الإصدار الخاص بفرق الضغط من عائلة CPB: يقيس ويعاير فرق الضغط تحت ضغط ساكن، بينما تعاير موازين الضغط التقليدية الضغط المطلق أو النسبي فقط.
في أي نطاق حراري يعمل الجهاز؟
درجة حرارة التشغيل المحيطة المحددة هي 18 … 28 °C، وهو ما يناسب ظروف المختبرات المعايرة.
