Solar Radiation Measurement(Silicon Pyranometer) Smart Sensor- NiuBoL

    Simple total radiation sensor (transmitter) can be used to measure the spectral range of 0.3-3μm total solar radiation, if the induction side down can measure the reflected radiation, plus shading ring can also measure the scattered radiation.

    The core device of the radiation sensor is a high-precision light-sensitive element, which has good stability and high precision; at the same time, a quartz glass cover made of precision optical cold processing is installed outside the sensing element, which effectively prevents the environmental factors from affecting its performance.

    The product can be widely used in meteorology, energy, agriculture, construction and other fields.

The total solar radiation sensor can be used to measure the total radiation under the sunlight. Sunshine Weather has developed the total solar radiation meter based on the principle of thermoelectric effect, for the principle of thermoelectric effect, the sensing element uses a wire-wound plated multi-contact thermopile with a high absorption rate black coating.

The hot contact is on the sensing surface, while the cold junction is located inside the body, and the hot and cold contacts produce a temperature difference potential. The output signal is proportional to the solar irradiance over a linear range.

To reduce the effect of temperature, a temperature compensation line is provided, and to prevent environmental effects on its performance, a two-layer quartz glass cover is used, which is made by precision optical cold working.

Secondly, small distributed power plants can use domestic and high precision products, at least one with the same tilt radiation meter with PV module tilt angle. According to the accuracy of solar radiation monitoring equipment, selective calibration once a year.

The importance of solar radiation sensor calibration cycle, high-quality meteorological and radiation sensors need to be calibrated periodically or their own life span is limited, for example, solar radiation meter at least 1 year to 2 years need to be calibrated once, mechanical wind speed anemometer, temperature sensors, etc. calibration to 1 year. Preventive maintenance, calibration, and replacement are essential to support the long term operation of the power plant.
