Sunshine Duration Sensor
Model: OSR01

The Global Radiation Pyranometer sensor is designedfor field measurement of global solar radiation in agricultural, meteorological, and solar energy studies The Solar Radiation Sensor, or solar pyrometer, measures global radiation, the sum at the point of measurement of both the direct and diffuse components of solar irradiance. It can also use to measure the sunshine duration hours with direct radiation>120W/m2.

The sensors transducer, which converts incident radiation to electrical current, is a silicon photodiode with wide spectral response. From the sensors output voltage, the console calculates and displays solar irradiance. It also integrates the irradiance values and displays total incident energy over a set period of time.

Spectral Range 300 1200 nm
Operational Temperature -40C to +85C
Output 0-25milli volts
Measuring Range 0 to 1750 W/m2
Response Time 10 s
Accuracy <5% (direct signal for clear sky)
Sensitivity Typically 90 A per 1000 W/m2
Sensor Cable Shielded cable with Molex connector
or custom cable as per user defined
connector available

Used extensively in solar energy studies for siteevaluations and monitoring, passive system analysis,irrigation scheduling and other environmental studies.

  • Features a silicon photovoltaic detector mounted in a fullycosine-correctedminiature head.
  • Can be mounted in any plane without affectingperformance.
  • In clear unobstructed daylight conditions comparesfavourably with first class thermopile type Pyranometer,but is priced at a fraction of the cost.
  • Spectral response does not cover full range of solarspectrum.
  • Includes anodized aluminium base with stainless steellevelling screws and a weatherproof spirit level.
  • Should only be used to measure unobstructed daylight(conditions of calibration). Not to be used undervegetation, artificial lights, in green houses, or forreflected solar radiation.
  • Crop management
  • Sky radiation
  • Irrigation control
  • Air Pollution Monitoring
