NJWxNet Sensor Information

This sensor is calibrated to measure total shortwave radiation. The evaporation of water from soil and the transpiration of water from plant leaves are partly determined by the intensity of shortwave radiation. An ideal pyranometer measures the entire solar spectrum, 280 to 2800 nm. However, about 90% of sunlight energy is between 300 to 1100 nm. Models PYR-P and PYR-S are calibrated to estimate all of the shortwave energy from sunlight. Apogee pyranometers are calibrated under sunlight over a multiple day period to a heated and ventilated Kipp & Zonen model CM21 precision reference radiometer.

The SP-110 uses a silicon photovoltaic detector mounted in a cosine-corrected head to provide solar radiation measurements for solar, agricultural, meteorological, and hydrological applications. Calibrated against a Kipp & Zonen CM21 thermopile pyranometer, the SP-110 accurately measures sun plus sky radiation for the spectral range of 360 to 1120 nm. The standard output is 0.2 mV per W/m², which provides a signal of 200 mV in full sunlight (1000 W/m²).

The CMP 3 pyranometer is an instrument for measuring the solar irradiance. The thermopile sensor construction measures the solar energy that is received from the total solar spectrum and the whole hemisphere (180 degrees field of view). The CMP 3 pyranometer is designed for continuous indoor and outdoor use. It is also intended for shortwave global solar radiation measurements in the spectral range from 300 to 2800 nm. The thermopile detector measures irradiance up to 2000 W/m² with response time < 18 seconds and typical sensitivity 10 μV/W/m² that varies less than 5 % from -10 ℃ to +40 ℃. Operating temperature range is -40 ℃ to +80 ℃ and the stability is better than 1 % per year. This Pyranometer does not require any power, it supplies a low voltage of 0-20mV in relation to the amount of incoming radiation.
