Radiation sensor to measure different kinds of radiation
Si-Global Radiation Sensor
The Si-Global radiations sensor is designed for routine measurement of solar radiation.
It is especially designed for:
- PV / solar energy module monitoring
- Agricultural evapotranspiration estimation
- Air pollution dispersion calculations using the Delta-T method
- Educational purposes
The sensor can be used under all weather conditions. The sensors measures the solar energy received from the entire hemisphere. It is ideal for measuring available energy for use in solar energy applications, plant growth, thermal convection, and evapotranspiration.
The Si-Global radiation sensor uses a photodiode detector, which creates a voltage output that is proportional to the incoming radiation. Also due to the unique design of the diffusor, its sensitivity is proportional to the cosine of the angle of incidence of the incoming radiation, allowing for accurate and consistent measurements.
It is easy to use. It can be directly connected to voltmeter, or Combilog. Direct readout in Watts per square meter (Wm2) can be derived from the measured voltage divided by the calibration coefficient.
