Research on the sensing technology for pressure measurement in the transient temperature flow field

Proceeding from analyzing unstable phenomenon of the planar diaphragm structure of the pressure sensor in the rapid temperature-changing field, the author broke free from conventional designing methods and adopted novel spherical-shell-shaped diaphragm structure to overcome the unstable phenomenon. The author also combined this technique with a series of corresponding technical measures to realize real-time precision measurement of rapid changing pressure in the transient temperature flow field.
