Solar Radiation Sensor
This solar radiation sensor or pyranometer is an instrument for measuring solar radiation. It measures the solar energy received from the entire hemisphere (180 degree field of view). Solar radiation varies significantly among regions. Season and time of day are major considerations, but surrounding terrain elevation, man-made obstructions, and surrounding trees can also cause large variations in locations with a small area.

About - Solar Radiation Sensor
RS-RA-*-AL-EX solar radiation sensor adopts photoelectric principle and can be used to measure the total radiation value under sunlight. The radiation sensor uses high-precision photosensitive elements, wide spectrum absorption, high absorption in the full spectrum range, and good stability. A dust cover with a light transmittance of up to 95% is installed outside the sensing element, and the dust cover is specially treated to reduce dust Adsorption can effectively prevent environmental factors from interfering with internal components, and can more accurately measure solar radiation.

Use - Solar Radiation Meter
Solar radiation meter installation
1. Use screws to pass through the mounting holes on the sensor to fix the sensor on the mounting position 2. Make sure the equipment is parallel to the ground (adjustable thumb screw and check the state of the horizontal bubble to determine whether it is parallel) 3. After the installation is complete, remove the protective cover
Solar radiation meter maintenance
1. The dust cover needs to be kept clean and clean, often wipe it with a soft cloth 2. There should be no water in the dust cover. If it encounters heavy rain, snow, ice, and other long-term weather, it is recommended to cover it.
FAQ - Solar Radiation Sensor
Solar radiation refers to the sun transmitting energy in the form of electromagnetic waves, and the electromagnetic waves and particle streams emitted by the sun into the universe. The energy transferred by solar radiation is called solar radiant energy. The value of the solar constant published by the World Meteorological Organization (WMO) in 1981 is 1368 W/m2. More than 99% of the solar radiation spectrum of the upper boundary of the earth’s atmosphere is between 0.15 and 4.0 microns in wavelength. About 50% of the solar radiation energy is in the visible spectrum (wavelength 0.4～0.76 microns), 7% is in the ultraviolet spectrum (wavelength <0.4 microns), 43% is in the infrared spectrum (wavelength> 0.76 microns), and the maximum energy is at a wavelength of 0.475 Micron.
The annual total solar radiation refers to the amount of solar radiant energy obtained in an area of 1 square centimeter in a year. Based on this, the distribution of the total solar radiation in a region or a country can be analyzed. There are two parts of solar radiation reaching the ground: one is that the sun is directly projected onto the ground in the form of parallel rays, which is called direct solar radiation. The second is that part of the energy of solar radiation is scattered in all directions with these particles as the center when it encounters air molecules or tiny dust. Part of the energy after scattering is projected from the sky to the ground, called scattered radiation, the sum of the two Called total radiation. It is the solar radiation that reaches the ground, of which direct radiation accounts for the main part.
Pyranometer is a device that measures solar irradiance from a hemispherical field of view incident on a flat surface. The SI units of irradiance are watts per square meter (W/m²).
The main difference between a pyranometer and a pyrheliometer is the purpose of measurement. Pyranometer is used to measure global solar radiation and hence it is used for both visible and UV. Pyrheliometer is used to measure direct solar radiation.
Our solar radiation sensor is IP65.
