مرسل درجة حرارة رقمي، إصدار مُركّب على الرأس
الوصف
تتميز طرازات OTMT84 وOTMT85 لمرسلات درجات الحرارة بوجود دخل عالمي لقياسات درجات الحرارة باستخدام موازين الحرارة المقاومة، والثرموازواج، وحساسات المقاومة ومصادر الجهد، مع دعم الاتصال FOUNDATION™ Fieldbus أو PROFIBUS ® PA. ويمكن تنفيذ ذلك مع أو بدون إجراء خطية مخصصة حسب طلب العميل. ويمكن تحقيق قياسات درجات الحرارة التفاضلية أو المتوسطة أو قياسات التكرار.
تتميز مرسلات درجات الحرارة بموثوقيتها، وثباتها على المدى الطويل، ودقتها العالية، وخيارات التشخيص الموسعة.
بالنسبة لـ FOUNDATION™ Fieldbus، يتوفر OTMT85 بوظائف LAS (Link Active Scheduler) ووحدة تحكم PID. تتيح هذه الوظائف إجراء تنظيمات مستقلة عن الماجستير داخل جهاز القياس الميداني.

الأسئلة والأجوبة
ما هو نطاق قياس درجة الحرارة؟
يعتمد النطاق على نوع الحساس المتصل؛ تشمل النطاقات المدعومة مثلاً -50 … +1768 °C للثرموازواج R و-200 … +850 °C لمستشعرات Pt100/Pt1000 و0 … +2315 °C للثرموازواج B.
ما الدقة التي يمكن توقعها؟
يحدد الدليل الانحراف القياسي النموذجي وفق DIN EN 60770؛ لا توجد قيمة دقة واحدة ثابتة في البيانات المتاحة.
ما الفرق بين OTMT84 وOTMT85؟
الطراز OTMT84 يدعم PROFIBUS® PA بالملف الشخصي 3.02، بينما يدعم الطراز OTMT85 FOUNDATION™ Fieldbus H1 ويضم إضافةً إلى ذلك وظائف LAS (Link Active Scheduler) ووحدة تحكم PID للتنظيم المستقل عن الماجستير داخل الجهاز الميداني.
هل يتوفر إصدار لمناطق خطرة؟
نعم، يتوفر إصدار Ex ia (أمان جوهري/FISCO) بشهادة ATEX رقم PTB 07 ATEX 2056 X للمناطق 0 و1 (II 1G Ex ia IIC T6...T4 Ga) وشهادة IECEx رقم BVS 08.0001X، كما يتوفر إصدار Ex ec.
كيف يتم التوصيل الكهربائي؟
عبر أطراف لولبية بمقطع يصل إلى 2.5 mm² (14 AWG)، مع تغذية DC 9 … 32 V.
ما هي درجة حرارة التشغيل المحيطية؟
يمكن للجهاز العمل في نطاق -40 … +85 °C من درجة حرارة البيئة المحيطة.
ما هي درجة الحماية IP00؟
تعني IP00 أن الجهاز غير محمي ضد اختراق الأجسام أو الماء؛ ولأنه مصمم ليُركَّب داخل علبة رأس (terminal head) فإن الحماية توفرها العلبة نفسها وليس الجهاز.
ما هي الشهادات العامة المتوفرة؟
حمل الجهاز شهادات CE وRoHS وNAMUR NE21 وNAMUR NE89 وEAC وREACH.

|---|---|---|
| Monitoring functionality when 2 sensors have been connected (dual sensor) | Redundancy | In the case of a sensor error (sensor break, lead resistance too high or outside the measuring range of the sensor) of one of the two sensors, the process value will be only based on the error-free sensor.Once the error is rectified, the process value will again be based on the two sensors, or on sensor 1. |
| Ageing control (sensor drift monitoring) | An error signalling on the output is activated if the value of the temperature difference between sensor 1 and sensor 2 is higher than a set value, which can be selected by the user. This monitoring only generates a signal if two valid sensor values can be determined and the temperature difference is higher than the selected limit value. (Cannot be selected for the 'Difference' sensor functionality, since the output signal already indicates the difference value). | |
