Strahlungssensoren / CS325DM-L
CS325DM-L Silicon Irradiance Reference Sensor

Überblick

Der CS325DM, hergestellt von IMT Solar alsSi-RS485TC-T, wird normaleweise als Referenzzelle bei der Überwachung von PV-Anlagen verwendet. Das Sensorelement wurde entworfen um einem PV-Modul zu ähneln, vor allem in der Spektralantwort. Datenausgabe erfolgt über Modbus RTU RS-485. Campbell Scientific baut einen Stecker am Sensor an, der es ermöglicht, das Kabel im Feld einfach zu ersetzten.

Funktionen und Vorteile

  • Robust, geeignet für weiten Temperaturbereich
  • Analoge und/oder digitale Ausgabe verfügbar
  • Spektrale Empfindlichkeit und Änderung beim Einfallswinkel korrespondieren mit kristallinen PV Modulen
  • Eingebaute Messung der Zell-Temperatur und Signal-Anpassung
