AP90T high frequency pressure sensor is used in military engineering, chemical explosion test, petroleum investigation and exploitation, petroleum well test, material, mechanics, civil engineering, geo-mechanics, traumatic medicine, hydraulic power mechanical test and other scientific tests.
AP90T high frequency pressure sensor is used in military engineering, chemical explosion test, petroleum investigation and exploitation, petroleum well test, material, mechanics, civil engineering, geo-mechanics, traumatic medicine, hydraulic power mechanical test and other scientific tests as well as modern instruments and meters, undistorted measurement of some frequently-changing dynamic pressure form, amplitude, and effective value with fast and steep pressure waveform rise shall be made. The high frequency pressure sensor has high intrinsic frequency, very short rise time, and wide and good response frequency band to ensure sufficient dynamic pressure measurement accuracy.
The high frequency pressure sensor is specially designed for this purpose. The high frequency pressure sensor 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. The high frequency pressure sensor boasts good elastic mechanics characteristics and its comprehensive performance is better than that of piezoelectric dynamic pressure sensor. Thus, high frequency pressure sensor is ideal for dynamic pressure measurement.
