مفتاح ضغط إلكتروني
الوصف
يُعد مفتاح الضغط الإلكتروني PSD-4 الحل الشامل لمهام أتمتة العمليات الصناعية - أيضًا في التطبيقات الصحية وتحت الظروف القاسية. وبفضل دقة تبلغ < ±0.5 % وانجراف طويل الأمد محدود للغاية، فإنه يضمن بشكل دائم تمثيلًا دقيقًا لضغط العملية لأكثر من 100 مليون دورة تحميل. يتوفر مفتاح الضغط بإشارة خرج رقمية، وكذلك بخرج تماثلي قابل للتحويل وقابل للضبط (scalable). بالإضافة إلى ذلك، يمكن مراقبته بسهولة أيضًا عبر التشخيص الذاتي.
المزايا
- مراقبة متقدمة للحالة عبر IO-Link
- مرونة أعلى، مخزون أقل
- تكامل سهل مقترن بوضوح قراءة جيد
- معايرة سريعة للمعاملات عبر 3 أزرار
