①. The total solar radiation sensor uses the photoelectric principle to measure the range of solar radiation at 0.3~3m. The radiation sensor adopts high-precision photosensitive element, wide spectrum absorption, high absorption and good stability in the full range; At the same time, a dust cover with a light transmittance of up to 95% is installed outside the sensing element. ②. The dust cover adopts special treatment to reduce dust adsorption, effectively prevent the interference of environmental factors on the internal components, and help to measure the amount of solar radiation more accurately. ③. The product adopts the standard communication protocol, which can directly read the current solar radiation value, and the method is simple. ④. Small and beautiful appearance, small installation space. Products are widely used in sectors such as solar energy utilization, agriculture, aging of building materials and air pollution to measure the energy of solar radiation. ⑤. High-precision sensor is adopted, and the absorption is high in the full spectrum range. ⑥. Comes with level and adjustment handwheel, convenient adjustment on site. ⑦. Standard Modbus-RTU protocol is adopted. ⑧. High transparent dust cover, good light sensitivity, special treatment, to prevent dust adsorption. ⑨. Colour: silver ⑩. Material: Metal ⑪. Type: RS485 ⑫. Package Contents: 1 x Solar Radiation Sensor ⑬. Due to different product batches, the appearance may vary. ⑭. Only the above package content, other products are not included. ⑮. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
