ترمومتر مقاومة مصغّر
الوصف
تُستخدم موازين الحرارة المقاومة لهذه السلاسل كأجهزة قياس حرارة عالمية لقياس وسائط سائلة وغازية في نطاق -50 ... +250 °C [-58 ... +482 °F]. الأجهزة آمنة بطبيعتها ومناسبة للاستخدام في المناطق الخطرة.
يمكن استخدامها لضغوط تصل إلى 140 bar [2,030 psi] مع أقطار حساسات 3 mm [0.12 in] وإلى 270 bar [3,916 psi] مع أقطار حساسات 6 mm [0.24 in]، وذلك اعتمادًا على نسخة الجهاز. جميع المكونات الكهربائية محمية ضد الرطوبة (IP67 أو IP69K) ومصممة لتحمّل الاهتزاز (20 g، اعتمادًا على نسخة الجهاز).
يتوفر ميزان الحرارة المقاوم بإخراج حسّاس مباشر أو مع مرسل مدمج، ويمكن تهيئته بشكل فردي عبر برنامج إعداد WIKAsoft-TT PC. يمكن ضبط نطاق القياس، والتخميد، وإشارة الخطأ وفقًا لـ NAMUR NE 043 ورقم TAG no.
