الوصف
حيثما يلزم بيان درجة حرارة العملية في الموقع أو في أماكن يصعب الوصول إليها، وفي الوقت نفسه يلزم تبديل الدوائر، فإن مقياس الحرارة المُشغَّل بالغاز مع جهات تلامس للتبديل يجد استخدامه.
بفضل تنوع التصاميم الممكنة، يمكن تكييف مقياس الحرارة المُشغَّل بالغاز طراز TGS73 بشكل مثالي مع أي توصيل للعملية أو أي موقع. ومع نسخة السيخ والقرص القابلين للضبط، يمكن ضبط الهيكل بدقة وفق زاوية الرؤية المطلوبة.
في نسخة لمبة التلامس (بدون تلامس مباشر مع الوسط)، يمكن قياس درجة الحرارة وتبديلها حتى عندما يكون قطر الأنبوب صغيرًا جدًا. تُخصَّص لمبة التلامس للتركيب الخارجي على الأنابيب والخزانات. وعند تركيب هذا الطراز من مقياس الحرارة، يجب التأكد من أن لمبة التلامس تكون في تماس مع موقع القياس على طولها الكامل.
الشكل أعلى: تركيب سفلي
الشكل أسفل: تركيب خلفي
تُنشئ جهات التلامس للتبديل (جهات تلامس إنذار كهربائية) أو تقطع الدوائر اعتمادًا على وضع مؤشر جهاز القياس الدال. يمكن ضبط جهات التلامس للتبديل عبر كامل مجال القياس. يتحرك مؤشر الجهاز (مؤشر القيمة الفعلية) بحرية عبر كامل مدى السلم، بغض النظر عن الضبط. يمكن ضبط المؤشر المُعدَّل عبر النافذة باستخدام مفتاح ضبط قابل للإزالة (مركّب على مقبس الكابل). كما يمكن ضبط جهات التلامس للتبديل المكوّنة من عدة جهات على نقطة ضبط واحدة. يتم إجراء التفعيل عند انتقال مؤشر القيمة الفعلية إلى ما يتجاوز نقطة الضبط المطلوبة أو إلى ما دونها.
كجهات تلامس للتبديل، تتوفر جهات تلامس مغناطيسية بنظام القَفْز (snap-action)، وجهات تلامس حثّية وجهات تلامس إلكترونية. يمكن استخدام جهات التلامس الحثّية في المناطق الخطرة. ولتفعيل وحدات التحكم المنطقي القابلة للبرمجة (PLC)، يمكن استخدام جهات التلامس الإلكترونية.

الأسئلة والأجوبة
ما مدى قياس درجة الحرارة المتاح لهذا الطراز؟
يتوفر الطراز TGS73 بمجالات قياس متعددة تمتد من −80 °C حتى +700 °C، مثل −20 … +100 °C أو 0 … +250 °C، ويُحدَّد المدى المناسب حسب التطبيق.
ما دقة الجهاز؟
فئة الدقة هي Class 1 per DIN 16196 عند درجة حرارة محيطة 23 °C ±10 °C.
ما أنواع جهات التلامس المتوفرة؟
جهات تلامس مغناطيسية بنظام القَفْز (snap-action)، وجهات تلامس حثّية، وجهات تلامس إلكترونية. الجهات الحثّية مناسبة للمناطق الخطرة، والإلكترونية لتشغيل وحدات PLC.
هل يمكن استخدام الجهاز في المناطق الخطرة؟
نعم، النسخ المزوّدة بجهات تلامس حثّية معتمدة للاستخدام في المناطق الخطرة بشهادات ATEX وIECEx.
ما هي توصيلات العملية المتاحة؟
تشمل الخيارات M18 x 1.5 وM20x1.5 وM24 x 1.5 وG ½ B وG ¾ B و½ NPT و¾ NPT.
ما مادة السيخ وما أبعاده؟
السيخ من الفولاذ المقاوم للصدأ Stainless steel 316، بطول 200 mm وقطر 6.0 mm.
ما درجة الحماية من الأتربة والماء؟
درجة الحماية IP65.
ما الذي يميّز هذا الطراز عن غيره؟
يجمع بين العرض المحلي لدرجة الحرارة وتبديل الدوائر في جهاز واحد بهيكل وسيخ من الفولاذ المقاوم للصدأ، كما تتوفر نسخة لمبة تلامس للقياس دون تلامس مباشر مع الوسط، مما يسمح بالقياس على أنابيب صغيرة القطر عبر التركيب الخارجي. ---

| Thermowell / Protection tube | In principle, the operation of a mechanical thermometer is possible without a thermowell / protection tube with low process-side loading (low pressure, low viscosity and low flow rates). However, in order to enable exchanging the thermometer during operation (e.g. instrument replacement or calibration) and to ensure a better protection of the measuring instrument and also the plant and the environment, it is advisable to use a thermowell / protection tube from the extensiveWIKA portfolio. → For further information on the wake frequency calculation of the thermowell / |
