Pyranometer Scattering Radiometer Solar Radiation Sensor For Solar Power Generation System Weather Station Supplier

Physical view of the Pyranometer installation

Scattered radiation sensor is made up of two parts: the total radiation sensor and the shading ring. The function of the shading ring is to ensure that direct solar radiation is continuously blocked from sunrise to sunset. The shading ring consists of a shading ring, a scale, a filament adjustment screw, a bracket and a chassis. The scale is fixed to the chassis with the bracket and should be fixed according to the geographical latitude of the place where it is erected. It can be widely used with meteorological stations and scientific departments to continuously determine the intensity of scattered radiation in the sky.

Solar Radiation Sensor: The meter is used to measure the total solar TBQ radiation in the spectral range of 0.3-3μm, and can also be used to measure the solar radiation incident to the oblique surface, such as induction face down can measure the reflected radiation, such as adding a shading ring can measure the scattered radiation.otal solar radiation sensor is an important ground meteorological observation instrument.

TBQ total radiation sensor adopts the principle of thermoelectric induction and works with various radiation recorders or radiation ammeters to accurately measure TBQ total radiation, reflected radiation, scattered radiation, infrared radiation, visible radiation, ultraviolet radiation, and long-wave radiation from the sun.

The double-layer glass cover is designed to reduce the effect of air convection on the radiation meter, and the inner cover is provided to cut off the infrared radiation from the outer cover itself.

TBQ Total Radiation Sensor Usage:  

The meter is used to measure the total solar TBQ radiation in the spectral range of 0.3-3μm, and can also be used to measure the solar radiation incident to the oblique surface, such as induction face down can measure the reflected radiation, such as adding a shading ring can measure the scattered radiation. Therefore, it can be widely used in solar energy utilization, meteorology, agriculture, building materials aging and atmospheric pollution and other departments to do solar radiation energy measurement.

The total solar radiation is the sum of direct solar radiation and solar scattered radiation received on the horizontal surface of an observation point on the Earth's surface. The total solar radiation consists of direct solar radiation intensity and scattered solar radiation.

Direct solar radiation: after weakening by atmospheric scattering and absorption, the solar radiation that reaches the surface directly along the direction of projection.

Solar scattered radiation: solar radiation through the atmosphere, by the scattering effect of atmospheric gases, dust, aerosols, etc., from all angles of the sky to the surface of part of the solar radiation.

How we monitor and utilize the total solar radiation through the total solar radiation sensor.

The total solar radiation sensor is an important ground meteorological observation instrument, and is also an indispensable equipment in the field of solar resource survey and photovoltaic power plant operation monitoring. The common types of solar radiation sensors are thermoelectric type and photoelectric type.

In order to meet the needs of customers, Jianda Renke has designed two products with different principles for total solar radiation sensors, thermoelectric total solar radiation sensor and photoelectric total solar radiation sensor, so that customers can better choose to monitor total solar radiation sensors according to their needs.

Thermoelectric Total Solar Radiation Sensor

The niubol thermoelectric total solar radiation sensor uses the thermoelectric principle to measure solar radiation in the spectral range of 0.3 to 3 μm. The sensing element is a wire-wound plated thermopile with a high absorption black coating on the sensing surface. Using the thermal effect of radiation, solar radiation is absorbed and converted into temperature difference electric potential.

And has a temperature compensation function, can more accurately measure the amount of solar radiation. Double glass cover is used above the induction surface, which not only can reduce the impact of air convection on the equipment, but also can block the radiation of the outer cover itself. And add radiation shield can measure scattered radiation.
