The high frequency dynamic pressure transducer is specially designed for military engineering, chemical explosion test, petroleum investigation and exploitation, petroleum well test, material, mechanics, civil engineering, geo-mechanics, traumatic medicine, hydraulic power mechanical test.
The dynamic pressure transducer adopts high performance chip of a foreign company, using micro machining technology to enable small effective dimensions and high intrinsic frequency of the integrated silicon chip. Dynamic pressure transducer has good elastic and mechanical properties, and its comprehensive performance is better than that of piezoelectric dynamic pressure sensor.
