Pyranometer Sensor mit 3-Punkt Libelle und Justageplatte

Das Pyranometer (Globalstrahlungssensor) dient der Erfassung der Globalstrahlung.

Die Globalstrahlung ist die aus dem oberen Halbraum auf die Erde einfallende direkte Sonneneinstrahlung und die indirekte diffuse Himmelsstrahlung. Sie umfasst einen Spektralbereich von ca. 200 bis über 3000 nm, d.h. vom UV- über den sichtbaren bis hin zum fernen infraroten Bereich.

Die Erfassung der Globalstrahlung kann u.a. durch Detektoren mit geschwärzten Thermoelementen erfolgen. Derartige Präzisionsmessgeräte sind meist sehr teuer, liefern mV-Signale und benötigen externe Messverstärker.

Auf Grund dessen empfiehlt sich für viele Anwendungen, z.B. im Agrar- oder Solarbereich, der Einsatz von Pyranometern mit angepassten Fotodioden als Detektor. Der erfasste Spektralbereich liegt zwischen ca. 350 und 1100 nm, d.h. bei über 90% der Globalstrahlung.

Unsere Pyranometer werden mit einem Präzisionspyranometer unter angenäherten Globalstrahlungsbedingungen abgeglichen. Somit sind die Messergebnisse sehr gut vergleichbar.

Unsere Pyranometer sind optimiert für den Einsatz an Datenloggern und Steuer- und Regelsystemen.

In der Grundausführung:

  • Messbereich zwischen 0 und 1250 W/m²
  • lineares Ausgangssignal von 0 bis 10 mV

Zusätzlich bieten wir folgende Optionen an:

  • integrierte Messverstärker (z.B. 0..1 V, 0..10 mA für 0..2000 W/m²; bei 12 VDC; oder nach Aufgabenstellung)
  • 3-Punktjustageplatten mit Dosenlibelle zum Nivellieren
  • Gegenplatten zur einfachen Montage an schmalen oder runden Flächen
  • Unterwasserausführungen
  • sehr schnelle Sensoren
