مقياس ضغط أنبوب بورَدون مع نقاط تلامس (مفاتيح)
الوصف
حيثما يلزم بيان ضغط العملية محليًا وفي الوقت نفسه يلزم تبديل الدوائر، فإن هذا switchGAUGE يجد استخدامه.
تقوم نقاط التلامس الخاصة بالمفتاح (نقاط التلامس الكهربائية للمفتاح) بفتح أو إغلاق دائرة التحكم الكهربائية اعتمادًا على موضع المؤشر الخاص بجهاز القياس الدال. يمكن ضبط نقاط التلامس الخاصة بالمفتاح على كامل مدى نطاق السلم (انظر DIN 16085)، ويتم تركيبها بشكل أساسي أسفل وجه الساعة، على الرغم من أنها قد تكون أيضًا جزئيًا فوق وجه الساعة. يتحرك مؤشر الجهاز (مؤشر القيمة الفعلية) بحرية عبر كامل مدى السلم، بشكل مستقل عن الضبط.
يمكن ضبط المؤشر المُعين باستخدام مفتاح ضبط قابل للإزالة عبر النافذة.
