נקודה חמה תרמית: אזור מקומי שחווה טמפרטורה גבוהה, לעתים קרובות מצביע על בעיות ציוד מתפתחות.

זיהוי עליית טמפרטורה: זיהוי של טמפרטורה חריגה מגביר איתות על תקלות פוטנציאליות בציוד.

בטיחות פנימית: מאפיין עיצוב המונע הצתה של אטמוספרות דליקות בתנאים רגילים או תקלות.

Corrosion Resistance: יכולת עמידה בפני התקפה כימית בסביבות אגרסיביות ללא פגיעה בביצועים.
