Introduction to direct solar radiation sensor equipment

The direct solar radiation sensor is also called the solar radiation sensor. The direct solar 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 an optimized straight tube design, good stability and high precision. At the same time, a quartz glass piece made of precision optical cold processing is installed outside the sensing element. A light shield is installed at the front end of the quartz glass piece installation barrel to effectively prevent environmental factors from affecting the sensor performance; the desiccant locking cover is equipped with The round glass observation window has a built-in color-changing silica gel desiccant, making it easy to observe 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 Pyranometer". It can be widely used in the measurement of direct solar radiation energy in departments such as meteorology, solar energy utilization, agriculture and forestry, aging of building materials, and atmospheric environment monitoring.
