The most popular pressure sensor independently dev

The pressure sensor independently developed by China was successfully loaded into the spacesuit editor's note: the "fth401 clothing pressure sensor" developed by the 48th Research Institute of China Electronics Technology Corporation to cut off the experimental motor source was successfully loaded into the extravehicular spacesuit backpack, ensuring the safety of spacewalk

it was learned from the 48th Research Institute of China Electronics Technology Corporation yesterday that the "fth403 cylinder pressure sensor" and "f th401 clothing pressure sensor focusing on quality improvement" developed by the Institute successfully solved the problems of high pressure resistance, oxidation resistance, no leakage, small size and high reliability required by the pressure sensor of the Shenzhou 7 astronaut ZhaiZhiGang's extravehicular spacesuit, and ensured the safety of spacewalk

it is understood that the "fth403 cylinder pressure sensor" is installed in Zhai Zhigang's extravehicular spacesuit backpack and hanging bag to measure the pressure change in the high-pressure oxygen cylinder in the clothing backpack and hanging bag, provide the basis for the use of the gas supply subsystem and the oxygen cylinder, and ensure that there is enough high-pressure oxygen for astronauts to travel in space. The "fth401 clothing pressure sensor" is only installed in the backpack of Zhai Zhigang's extravehicular spacesuit to measure the breathing pressure of astronauts in the spacesuit and ensure that the environmental pressure in the clothing meets Zhai Zhigang's work needs and life safety needs for spacewalk
