The key components for flying into space (Quartz flexible accelerometers)

The quartz flexible accelerometer is actually a sensor that can accurately measure acceleration and is a member of the accelerometer family. The sensor used in our daily mobile phones is called MEMS accelerometer, but the quartz flexible accelerometer is much more accurate, and has a wider range of applications. It has been widely used in aerospace, aviation, ships, weapons, petroleum, geotechnical engineering and many other fields, providing accurate acceleration measurement signals for navigation, guidance, control, leveling, monitoring, etc. of various systems.

The first obstacle for quartz flexible accelerometers in their journey to space is the large mechanical impact during the launch process. Compared to a giant like a rocket, the quartz flexible accelerometer is insignificantly small, but it is this small size that can bring out the advantages of high-precision measurement. It is also this precise measurement requirement that makes the quartz flexible accelerometer appear to be more "delicate" and difficult to withstand the large impact of the rocket-satellite separation during the rocket launch process. Therefore, the quartz flexible accelerometer needs to be specially designed so that when a large mechanical impact comes, the impact on the quartz flexible accelerometer can be quickly resolved.

Space travel is romantic, but as the altitude increases, the air will become thinner and thinner, and the atmospheric pressure will become lower and lower, eventually approaching a vacuum. In order to ensure the measurement accuracy of the quartz flexible accelerometer, the quartz flexible accelerometer must be sealed, that is, the quartz flexible accelerometer must be covered with an airtight "outer coat". In order to fully ensure the reliability of the seal, the space environment is simulated, and the sealed outer coat is subjected to harsh tests such as vibration and impact. After thousands of trials and tribulations, the sealed outer coat of the quartz flexible accelerometer is finally available, providing a solid barrier for the quartz flexible accelerometer to work in a vacuum environment.

Our HTS-JA6 series high temperature quartz flexible accelerometers are resistant to high temperatures, with a maximum temperature of 185°C. They are highly shock resistant and can withstand shocks of up to 1000 g/0.5ms. They have the advantages of high accuracy, small size, low power consumption, high resolution, fast response, good reliability, low cost, and strong overload capacity, and are widely used in aerospace systems.
