CS300-QD Pyranometer for RAWS-F Station
利用できるサービス

概要

The CS300-QD, manufactured by Apogee, measures total sun and sky solar radiation for solar, agricultural, meteorological, and hydrological applications. Its spectral range of 360 to 1120 nanometers encompasses most of the short-wave radiation that reaches the Earth's surface. The CS300-QD supports continuous outdoor use.

利点と特徴

  • Compatible with most Campbell Scientific data loggers
  • Designed for continuous, long-term, unattended operation in adverse conditions
  • Measurement waveband of 360 to 1120 nm
  • Dome-shaped head prevents water from accumulating on the sensor head

詳細

With this version of the CS300 pyranometer, the cable has a military style connector instead of pigtails for attachment to the RAWS-F Fire Weather Quick Deployment Station.

The CS300-QD uses a silicon photovoltaic detector mounted in a cosine-corrected head to provide solar radiation measurements. Its dome-shaped head prevents water from accumulating on the sensor head. To eliminate internal condensation, the sensor head is potted solid and the cable is shielded with a rugged Santoprene casing. The CS300 is calibrated against a Kipp & Zonen CM21 thermopile pyranometer to accurately measure sun plus sky radiation.

互換性

The military style connector attaches to the RAWS-F Fire Weather Quick Deployment Station, which has an on-board CR1000.

Sensor Mounts

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 or a tripod or tower mast using the CM225 mounting stand. The CS300 should be mounted away from all obstructions and reflective surfaces that might adversely effect the measurement.

Data Logger Considerations

One differential analog input channel per probe is required.
