الوصف

تم تصميم مقياس الحرارة ثنائي المعدن طراز TG58SA خصيصًا لتلبية متطلبات التطبيقات الصحية.

تتم وظيفة نقل درجة الحرارة بشكل ميكانيكي بحت عبر ملف ثنائي المعدن داخل الساق. ولل تطبيقات التي تتطلب قياسًا لا يحتاج إلى طاقة مساعدة، مثلًا مع الوعاء/الناقلات المتنقلة، فإن TG58SA مع السائل (الهيكل) مناسب بشكل خاص.

على الجزء الخلفي من الهيكل، يمكن تصحيح نقطة الصفر بسهولة.

تتيح الساق ذات القاعدة شبه الكروية، بالاقتران مع وصلات عمليات التعقيم (مثل المشبك، VARINLINE ® )، إجراء توصيل خالٍ من المساحة الميتة مع العملية.

المزايا

الأمان من خلال الإشارة إلى درجة الحرارة ميكانيكياً
سهولة التنظيف بفضل التصميم الصحي لعلبة الجهاز والأجزاء الملامسة للمائع
ضبط سهل لنقطة الصفر
مقاومة عالية لارتفاع درجة الحرارة

الأسئلة والأجوبة

ما هي نطاقات القياس المتاحة للطراز TG58SA؟

يتوفر الطراز بعدة نطاقات قياس تتراوح بين ‎-40 … +40 °C‎ و‎20 … 180 °C‎، مثل ‎0 … 100 °C‎ و‎10 … 90 °C‎ و‎20 … 130 °C‎.

ما مدى دقة القياس؟

الدقة هي Class 1 وفقًا للمعيار EN 13190.

ما هي وصلات العملية المتاحة؟

تتوفر وصلات Clamp connection وDIN 11864-1 وDIN 11864-2 وDIN 11864-3 وVARINLINE®، مما يتيح توصيلًا خاليًا من المساحة الميتة مع العملية.

هل يمكن استخدامه مع وسائط عند درجات حرارة مرتفعة؟

نعم، يتحمل الوسط درجات حرارة من ‎-50 … +150 °C‎، كما يتميز الطراز بمقاومة عالية لارتفاع درجة الحرارة.

ما هي شهادات النظافة التي يحملها؟

الطراز معتمد وفق 3-A وEHEDG Class I، وهو مصمم لتطبيقات صحية مناسبة لعمليات CIP وSIP.

هل يناسب المناطق الخطرة؟

نعم، لديه موافقات انفجار: II 2G Ex h IIC T6 … T1 Gb X للمنطقة 1 (غاز) وII 2D Ex h IIIC T85 … T450 °C Db X للمنطقة 21 (غبار).

ما الذي يميز TG58SA عن غيره من الترمومترات ثنائية المعدن؟

تصميمه الصحي بأجزاء ملامسة من Stainless steel 316L وقطر ساق 6.35 mm، مع وصلات تعقيم خالية من المساحة الميتة، وإمكانية ضبط نقطة الصفر بسهولة من الجزء الخلفي للهيكل — وهو مناسب بشكل خاص للتطبيقات التي لا تحتاج إلى طاقة مساعدة مثل الوعاءات المتنقلة. ---
