Grenzabweichungen

Die Grenzabweichungen der Widerstände sind in der DIN EN 60751 in zwei Klassen eingeteilt. Wir verbauen grundsätzlich nur die Klasse A, da die Preisdifferenz zur Klasse B nur minimal ist.

Maximale Abweichungen Klasse A
Maximale Abweichung bei 0°C (+/-) 0,15°C
Maximale Abweichung bei 200°C (+/-) 0,55°C
Maximale Abweichung bei 400°C (+/-) 0,95°C
Maximale Abweichung bei 600°C (+/-) 1,35°C

Ansprechzeiten

Diese Halbwertzeiten betragen in Wasser bei

  • Glas - Messwiderständen: zwischen 0,14 und 0,8s
  • Keramik - Messwiderständen: zwischen 0,2 und 0,4s
  • Schicht - Messwiderständen: zwischen 0,1 und 0,3s

Diese großen Streubreiten zeigen an, dass diese Werte stark an die Bauform des Messwiderstandes gekoppelt ist.

Bei einem Messeinsatz, z.B. Ausführung nach DIN 43762, liegt diese Halbwertzeit zwischen 6 und 9 Sekunden. Bei einem Thermofühler mit Messeinsatz und Schutzarmatur, z.B. nach DIN 43772, zwischen 36 und 40 Sekunden.
