scattered radiation is the solar radiation that changes direction by scattering the particles through atmospheric molecules, water vapor, dust, etc., which is also called sky scattered radiation. The intensity of the solar scattered radiation is related to the incident angle of the solar radiation, atmospheric conditions (the amount of particles such as cloud volume, water vapor, sand particles, smoke and dust) and the ground reflectivity. When the turbidity of the sky increases, the path through which the sun passes is blocked, the degree of scattered radiation will increase; when the local reflectivity increases, the scattered radiation will also increase.
scattered radiation transmitter uses the principle of thermoelectric detection to accurately measure the current solar scattered radiation value, and upload the data in real time to the environmental monitoring platform or the user's own platform through 485/4G/network ports, etc., and can log in to the platform at any time to view the strength and weakness of the solar scattered radiation data. The induction element in the scattering radiation transmitter uses a wound coiled plating thermopile, and the sensing surface is a black coating with high absorption. Using the thermal effect of radiation, solar radiation is absorbed and converted into temperature-differential electromotive force.
Tips: Why does the scattering radiation transmitter choose the thermoelectric detection principle rather than the photoelectric?
thermoelectric spectrum response range is wider than that of photoelectric meter, and the measured data will be more accurate. The measurement core of the
scattering radiation transmitter - the total solar radiation transmitter uses an aluminum alloy shell, with a protection level of IP67, which is completely suitable for field measurement, making it anti-rain, anti-oxidation and corrosion resistance.
Popular science: Advantages of aluminum alloy shell:
1, light weight, aluminum alloy is the lightest metal among practical metals, which is convenient for users to save time and effort when mobile devices.
2 has good corrosion resistance. The aluminum alloy itself will automatically form a dense oxide film when it comes into contact with air. In addition, the company's anti-corrosion process has been carried out on it, which is even more strengthened!
3 has good electromagnetic shielding characteristics to avoid scattering radiation transmitter is disturbed by external interference during operation.
double-layer glass cover -
scattering radiation transmitter is a transparent double-layer glass cover with a transmittance of up to 95% above the sensing surface of . It has good sensitivity, which not only can reduce the impact of air convection on the device, but also block the radiation of the outer cover itself. And the surface has been specially treated and has dustproof function.
protective cover—
is located above the double-layer glass cover, which can effectively protect the double-layer glass and prevent dust from adsorption.
Note: When using the scattering radiation transmitter, be sure to remove the protective cover to avoid affecting the measurement process.
Radiation protection mask -
can avoid other elements in the environment interfering with the process of product measuring scattered radiation values, ensuring accurate data measurement.
In order to prevent the output signal from drifting with the change of the surrounding ambient temperature after a long period of time, we specially added the temperature compensation function to it, which can achieve the purpose of eliminating the impact of temperature changes on the product output signal within a certain range. Enhance the product's environmental adaptability and avoid measurement accuracy being affected by external temperature changes.
scattering halo ring can ensure that the direct radiation of the sun can be blocked from sunrise to sunset, so that the equipment can accurately measure the sun's scattering radiation value. The scattering halo ring is composed of a halo ring, a ruler, a screw adjusting spiral, a bracket, and a chassis. After fixing the ruler and bracket on the chassis, the measurement is fixedly performed according to the geographical latitude of the erected location. The data measured by
scattered radiation transmitter will be uploaded to the environmental monitoring platform in real time. The platform has a variety of functions to meet the various requirements of users when using scattered radiation transmitters.
scattering radiation transmitter will transmit data to the environmental monitoring platform in real time when it is working normally. Users can log in to the platform on their computers and view data on the scattering radiation intensity changes at any time.
Users can use time to filter and query past data in the history function at any time, generate daily reports, monthly reports, quarterly reports, and annual reports according to usage needs, and export and print them, so as to facilitate data comparison, and also perform paper backups. The large-screen visualization function in the
environment monitoring platform allows users to see the location of the scattered radiation transmitter and the online/offline status, and quickly grasp the changes in the scattered radiation intensity data.
In addition to the above, the environmental monitoring platform also has functions such as electronic maps, account grading, over-limit alarms, multi-party compatibility, secondary development, etc.
scattering radiation transmitters are widely used in industries that deal with solar radiation, such as meteorological fields, agriculture fields, building materials aging and air pollution, and can be used to measure sky (solar) radiation.
