Direct radiation sensor equipment introduction
Direct radiation sensor can be used to measure the intensity of direct solar radiation in the spectral range of 0.28-3μm. The core component of the radiation sensor is a high-precision photosensitive element, with a precise straight tube optimized design, good stability and high precision; 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 at the front end of the quartz glass sheet installation tube, which effectively prevents environmental factors from affecting the performance of the sensor; the desiccant locking cover is equipped with a circular glass observation window and a built-in color-changing silica gel desiccant, which is convenient for observing the water absorption of the desiccant.
This product complies with the technical specifications of ISO9060 and WMO World Meteorological Organization (CIMO Guide) and the latest Chinese meteorological standard "QX/T 20-2016 Direct Pyrheliometer". It can be widely used in the measurement of direct solar radiation energy in meteorology, solar energy utilization, agriculture and forestry, building material aging, atmospheric environment monitoring and other departments.
