The world's first international standard for solar photovoltaic glass
The world's first international standard for solar photovoltaic glass was successfully established by Shenzhen Chuangyi Technology Development Co., Ltd., a high-tech enterprise in Shenzhen's new energy industry. The company will become the convener of the international standardization working group in the future. This is also China's solar photovoltaic industry. The first successful international standard in the field. Yesterday, members and experts from China, Belgium, the United Kingdom, Germany, France, and Japan all participated in the “ISO/TC1602010 Annual Meeting†held in Shenzhen. Huang Jianbin, the deputy secretary-general of the National Glass Standardization Technical Committee for Buildings, stated that since 2000, China's glass industry has significantly increased its production and technology, and it has become the world's largest producer of glass. However, the standardization in the field of glass is still relatively weak, and there is a phenomenon of disorderly and disorderly systemic revision. “Because the standardization committees have some problems in some projects, lack of communication between each other, resulting in the duplication of standard projects; or due to different starting points and different understanding of the industry, the emergence of standards by incapable enterprises or units Phenomenon, the lack of standard content advanced and impartial.†Huang Jianbin said that this makes the entire industry involved in the international standard system, revision and other efforts is far from enough. In the increasingly frequent international trade, it is very likely to make China's glass manufacturing enterprises in a disadvantageous position. On the other hand, China's glass industry also faces many problems, such as excess production capacity, unreasonable industrial structure, and extensive production methods. Huang Jianbin said that in the next few years, the glass industry will change the mode of economic growth, guide and allocate limited essential resources to optimize stocks and cultivate new growth points. Among them, the integrated application technology of solar photovoltaic glass and building is one of the focuses of R&D. According to relevant person in charge of the Shenzhen Institute of Standards and Technology, it is difficult to make greater breakthroughs in the traditional international standardization field, and solar photovoltaic is a new industry. The gap between the Chinese enterprises and the world's enterprises is not big. In the integrated application of solar photovoltaic glass products and their combination with buildings, it is basically synchronized. Shenzhen enterprises have obtained this standard project, which has special significance for Shenzhen and the nation in understanding the development direction of the industry technology in the future, improving the overall R&D innovation capability and core competitiveness of the industry, and obtaining the strategic high point of the industry. Water level sensor, alose called hydrostatic pressure level sensors, submersible level sensors, which are submersible level sensors used for measuring the level of liquids (including corrosive liquids) in deep tanks or water in reservoirs. It provide accuracy and reliability across a wide range of applications. Based on the principle that the measured liquid static pressure is proportional to the height of the liquid, the advanced isolation type diffusion silicon sensor or ceramic capacitive Pressure Sensor is used to convert the static pressure into electrical signals, and then through temperature compensation and linear correction, into standard electrical signals (generally 4-20mA/1-5VDC). water tank level sensor, pressure level sensor, submersible level sensor, hydrostatic level sensor, water Level Transmitter Xi'an Gavin Electronic Technology Co., Ltd , https://www.gamicos-meas.com
