Häufig gestellte Fragen

Für welche Medien ist der RLSW7 geeignet?

Er überwacht wässrige Flüssigkeiten bis 30% Glykol sowie Luft- und Gasströmungen. Messbereiche: 0,03–3 m/s für Wasser, 0,5–20 m/s für Luft

Wie stelle ich den Schaltpunkt ein?

Über zwei Potentiometer an der Elektronikeinheit. Grob-Poti für den Grundwert, Fein-Poti für die exakte Anpassung bei laufender Nennströmung.

Welche Ein-/Auslaufstrecken sind erforderlich?

Mindestens 5 × Rohr-Ø als Einlauf und 3 × Ø als Auslauf, um Turbulenzen zu vermeiden

Für welche Medientemperaturen ist das Gerät ausgelegt?

Medium -10…80 °C (Wasser) bzw. -25…80 °C (Luft); Umgebung -20…60 °C. Temperaturgradient max. 15 K/min

Wie hoch ist die Schaltleistung des Relais?

250 V AC, 6 A (1,5 kVA). Mindestschaltlast 10 mA / 5 V DC

Gibt es Einschränkungen beim Kühlmittel?

Ja. Glykolanteile über 30% können zu Fehlmessungen führen.

Welche Versorgungsspannungen sind verfügbar?

24 V AC/DC ±5% (3 VA) oder 230 V AC ±6% (4,5 VA)

Wie signalisiert der RLSW7 Betriebszustände?

Grüne LED zeigt Netzspannung; gelbe LED leuchtet bei erreichtem Strömungsschwellwert
