SP230SS
SP230SS
OrderableHeated Pyranometer
Overview
The SP230SS pyranometer, manufactured by Apogee, includes a 0.18 W internal heater and an elevated base that allow it to provide solar radiation measurements during the most severe weather. Its small heater draws just 15 mA of current, allowing it to be powered by a small solar panel and battery─even on days with a short duration of daylight and at high latitudes (far away from the equator).
This pyranometer features an IP67-rated, marine-grade 316L connector that allows the user to easily swap sensors for recalibration or to replace damaged cables.
Key Advantages
Heater prevents snow, frost, and dew accumulation
Technical Description
The 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.
Benefits
- Designed to prevent snow, frost, and dew accumulation
- Heater uses 1/80<sup>th</sup> of the power that other heated pyranometers use, making it ideal for remote battery-powered applications
- Measurement waveband of 360 to 1120 nm
- Compatible with most Campbell Scientific data loggers
- Dome-shaped head prevents water from accumulating on the sensor head

Mounting
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.
