Ideal für Langzeitmessugen
Überblick
Der EE181 ist ein robuster, sehr genauer Sensor für Temperatur und Luftfeuchte (RH), ideal für Langzeitanwendungen mit wenig Wartung. ein neuartiger spezieller Schutzlack auf dem Feuchteelement verlängert dessen Lebensdauer und schützt es vor Salz, Staub, Schmutz und anderen Verunreinigungen. Ein 1000 Ω PRT misst die Temperatur im Bereich -40°C bis +60°C. Für optimale Ergebnisse sollte der EE181 jedes Jahr rekalibriert werden.
Funktionen und Vorteile

- Genau, zuverlässig und robust
- Besonders gute Langzeitstabilität
- Großer Temperaturbereich
- Kompakt und leicht auszutauschen
- Geringer Stromverbrauch
- Kompatibel mit allen Campbell Scientific Datenloggern

Additional Compatibility Information
Sensor Mounts
When exposed to sunlight, the EE181 must be housed in a 10-plate solar radiation shield. Campbell Scientific recommends the MetSpec RAD10E, which uses a double-louvered design that offers improved sensor protection from driving rain, snow, and insect intrusion. This shield also has lower self-heating in bright sunlight combined with higher temperatures (> 24°C [~75°F]) and low wind speeds (< 2 m s-1 [~4.5 mph]), giving a better measurement.
The EE181 will work with R. M. Young 10-plate radiation shields (41003-5 or 41003-5A), but these shields require a special adapter (pn 28415) to accommodate the sensor girth.
The RAD10E and 41003-5 attach to a crossarm, mast, or user-supplied pipe with a 2.5 to 5.3 cm (1.0 to 2.1 in.) outer diameter. The 41003-5A radiation shield attaches to a CM500-series pole or a user-supplied pole with a 5.1 cm (2.4 in.) outer diameter.
