Recently, the researchers of the Shanghai Institute of Technology of the Chinese Academy of Sciences have compiled the "Technical Conditions for the Upgrade and Screening of High-Power Semiconductor Lighting Devices" for China's manned transport spacecraft for the first time, and successfully selected the requirements for the EEE warranty program for aerospace components and the application requirements for the environment outside the cabin. The high-power semiconductor lighting device has been successfully verified in the mission of the Shenzhou-7 manned spacecraft, and it has explored a feasible technical approach for the application of high-quality LED devices with high quality in the aerospace field. With the support of the Shanghai Municipal Science and Technology Commission, the “High Power LED Screening Specification for Aerospace Lighting†project was also launched last year and will be completed within the year.
Semiconductor lighting device LED (LED) has high luminous efficiency, low energy consumption, low working voltage, volume filial weight, high reliability, etc. It belongs to a new type of solid-state lighting source, with obvious advantages and broad prospects in the field of aerospace lighting. .
According to the data research, there are no high-quality LED lighting devices at home and abroad, and there are no screening specifications for this type of high-quality devices at home and abroad. Therefore, the development of screening specifications for high-quality grade high-power LEDs has become a prerequisite for the application of this type of device to space lighting.
DN25MM digital magnetic flowmeter has long - term high measurement accuracy. Electromagnetic Flow Meter is actually unaffected by the physical properties of the fluid. The measurement accuracy can reach 1,0.5.
magnetic flow Meters have no mechanical or moving parts and usually do not require maintenance.
em flow meter is suitable for all liquid flow tests with conductivity greater than 5. The change of conductivity does not affect the change of performance.
The best integrated circuit in the world is used to eliminate the influence of excitation switch, and the compensation method of excitation current is used to achieve the optimal stability of the product.
Easy to operate, the flow meter is automatically set in the range of 0 ~ 10m /s, without changing the measuring range.
