ترمومتر مقاومة مصغّر من OEM
الوصف
تُستخدم موازين الحرارة المقاومة من هذه السلاسل كأجهزة قياس حرارة عالمية لقياس وسائط سائلة وغازية في نطاق -50 ... +250 °C [-58 ... +482 °F]. وللاستخدام في المناطق الخطرة، تتوفر إصدارات ذات أمان جوهري. ويمكن استخدامها لضغوط حتى 140 bar [2,030 psi] مع أقطار حساسات 3 mm [0.12 in] وحتى 270 bar [3,916 psi] مع أقطار حساسات 6 mm [0.24 in]، وذلك حسب إصدار الجهاز. جميع المكونات الكهربائية محمية ضد الرطوبة (IP67 أو IP69K) ومصممة لتحمّل الاهتزاز (20 g، حسب إصدار الجهاز).
يتوفر مقياس الحرارة المقاوم مع خرج حسّاس مباشر أو مُرسِل 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. يمكن ضبطه.
يمكن اختيار طول الإدخال، ووصلة العملية، ونوع الحساس وطريقة التوصيل لكل منها لتطبيقه المعني ضمن معلومات الطلب. يتكوّن طراز TR31 لمقياس الحرارة المقاوم من أنبوب غاطس/أنبوب حماية مع
