Direct radiation sensor device introduction
Direct radiation sensor is used to measure solar radiation and can monitor the intensity of direct solar radiation. It can be applied in many fields.Direct radiation sensor can be used to measure the direct radiation intensity of the solar spectrum in the spectral range of 0.28-3μm. The core device of the radiation sensor is a high-precision photosensitive element, with an optimized design of the precise collimator, good stability and high accuracy; at the same time, a quartz glass sheet made of precision optical cold processing is installed outside the sensing element, and a light shield is installed on the front end of the quartz glass sheet installation cylinder, which effectively prevents the influence of environmental factors on the sensor performance; the desiccant lock cover is equipped with a circular glass observation window, and a built-in color-changing silicone desiccant, which is convenient for observing the water absorption of the desiccant.
This product complies with the requirements of ISO9060 and WMO World Meteorological Organization Specification (CIMO Guide) and the latest Chinese meteorological standard "QX/T 20-2016 Direct Radiation Table". It can be widely used in the measurement of direct solar radiation energy in meteorological, solar energy utilization, agriculture and forestry, building material aging and atmospheric environment monitoring and other departments.
