What is the total solar radiation sensor?
With the advancement of science and technology, people's understanding of the sun has gradually deepened, and the mystery of solar radiation has begun to be gradually unveiled. In order to improve the utilization rate of total solar radiation and make it play a greater role, the industry uses solar total radiation sensors to monitor total solar radiation and make reasonable plans based on its intensity. What is the total solar radiation? What is the total solar radiation sensor? The total solar radiation is the sum of the direct radiation received from the sun and the scattered radiation from the sun on the horizontal plane of a certain observation point on the earth's surface. The total solar radiation is composed of direct solar radiation intensity and solar scattered radiation. Direct solar radiation: After being weakened by atmospheric scattering and absorption, the solar radiation that reaches the surface directly along the projection direction. Solar scattered radiation: When solar radiation passes through the atmosphere, it is scattered by gases, dust, aerosols, etc. in the atmosphere, and reaches the surface of the earth from various angles in the sky. So in industry and production, how do 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 it is also an indispensable equipment in the field of solar energy resource survey and photovoltaic power plant operation monitoring. The common types of total solar radiation sensors are pyroelectric and photoelectric. In order to meet the needs of customers, two products with different principles are designed for the total solar radiation sensor, the pyroelectric total solar radiation sensor and the photoelectric total solar radiation sensor, so that customers can better choose and monitor the total solar radiation according to their needs. sensor. 1. Pyroelectric total solar radiation sensor The pyroelectric total solar radiation sensor (model: RS-TRA-N01-AL) adopts the pyroelectric principle and can be used to measure solar radiation with a spectral range of 0.3~3μm. The sensing element adopts a wire-wound electroplating thermopile, and the sensing surface is a black coating with high absorptivity. Using the thermal effect of radiation, it absorbs solar radiation and converts it into thermoelectromotive force. It also has a temperature compensation function, which can accurately measure solar radiation. The double-layer glass cover above the sensing surface can not only reduce the influence of air convection on the device, but also block the radiation of the cover itself. And add a radiation shield to measure scattered radiation. The product adopts standard Modbus-RTU 485 communication protocol and two signal output methods of analog quantity, which can directly read the current total solar radiation value, and the wiring method is simple. The appearance is beautiful, and the installation space is small. 2. Photoelectric total solar radiation sensor The photoelectric total solar radiation sensor (model: RS-RA-N01-AL) adopts the photoelectric principle and can be used to measure solar radiation with a spectral range of 0.3~3μm. The radiation sensor uses high-precision photosensitive elements, wide spectrum absorption, high absorption in the full spectrum range, and good stability; at the same time, a dust cover with a light transmittance of up to 95% is installed outside the sensing element, a high transparent dust cover, and good sensitivity. , The dust cover adopts special treatment to reduce dust absorption, effectively prevent environmental factors from interfering with internal components, and can more accurately measure solar radiation. It also comes with a level gauge and an adjustment handwheel, which is convenient for on-site adjustment. The product adopts the standard Modbus-RTU 485 communication protocol, which can directly read the current solar radiation value, and the wiring method is simple. The appearance is small and beautiful, and it takes up little installation space. Both of the two total solar radiation sensors can be widely used in solar energy utilization, meteorology, agriculture, building materials aging and air pollution and other departments to measure solar radiation energy.
sensor solution is not something to be ignored or taken for granted. It is there to keep your OEM sensor comfortable year round. To find a cost effective solution, turn to Hunan Rika Electronic Tech Co.,Ltd .
