Das SP230SS Pyranometer von Apogee verfügt über eine interne Heizung mit 0,18 W und eine erhöhte Basis, so dass auch bei schwierigen Witterungsverhältnissen Sonnenstrahlung gemessen werden kann. Die Heizung braucht nur 15 mA Strom, daher kann der Sensor auch über eine Batterie und eine Solarzelle betrieben werden ─ auch an kurzen Tagen mit wenig Licht und hohen Breitengraden (entfernt vom Äquator).
An diesem Pyranometer angebracht ist 316L Stecker mit Schutzklasse IP67, so dass man den Sensor einfach austauschen kann, z. B. zur Rekalibrierung oder wenn etwas beschädigt ist.
Lesen Sie mehrThe SP230SS uses a silicon photovoltaic detector mounted in a cosine-corrected head to provide solar radiation measurements. It is calibrated against a Kipp & Zonen CM21 thermopile pyranometer to accurately measure sun plus sky radiation for the spectral range of 360 to 1120 nm. The SP230SS outputs a millivolt signal that Campbell Scientific data loggers can measure.
Note: Sensors calibrated to the 360 to 1120 nm spectral range should not be used under vegetation or artificial lights.

Accurate measurements require the sensor to be leveled using a 18356 leveling fixture. This leveling fixture incorporates a bubble level and three adjusting screws. The 18356 mounts to a crossarm using the CM225 mounting stand. The SP230SS should be mounted away from all obstructions and reflective surfaces that might adversely affect the measurement.
