Solar Irradiance Sensor
A thermo-compensated reference cell, individually calibrated for the measurement of solar irradiation, housed in 430 BA Inox.
For synchronisation with iVolt™.
FEATURES
- Measures solar radiation with temperature compensation
- Synchronisation with iVOLT™
- Calibrated in a laboratory
- 2 Pt100 temperature probes (Tcell, Tpanel)
- Input for wind direction and speed anemometer
- Inox case
- Digital data computation with internal micro-controller
- Integrated battery charger
The SunCel™ 3.0 sensor has been appositely studied for the measurement of solar radiation with temperature adjustments for synchronisation with the data registered by iVolt™.
Solar irradiation is measured via a silicon photovoltaic cell calibrated in a laboratory, the temperature of which is constantly monitored to carry out measurement adjustments.
The sensor is furthermore fitted with two more thermometric probes. The first is a adhesive contact probe for the measurement of the temperature of a photovoltaic panel. The second (optional) is external to the case of the probe, and is used for measuring the ambient temperature. The data acquired by the sensors is processed by a micro-controller which, taking into account the calibration and adjustment values, provides a linearised measurement with an analogue output (voltage or current loop) or on a protocol (USB or 485).
The unit has a 430 BA Inox steel box and can be optionally fitted with a forced ventilation system for the measurement of air temperature. Furthermore, an input for an anemometer for the measurement of wind direction and speed is available. The SunCel™ 3.0 sensor is therefore an accurate device for the measurement of solar irradiation which, integrated with iVolt™, provides the data necessary for testing the photovoltaic installation.
