• • • Overview of Product • • •
In such scientific test and modern instruments and meters as military engineering, chemical explosion test, petroleum investigation and mining as well as petroleum well test, material, mechanics, civil engineering, geo – mechanics, trauma medical, hydraulic power mechanical test etc, undistorted measurement of some frequently – changing, fast and steep pressure wave form rise is made for the dynamic pressure form, amplitude, and effective value, it is required that the pressure sensors used shall have high intrinsic frequency, very short rising time, and wide and good response frequency band to ensure sufficient dynamic pressure measuring accuracy. MS390 high - frequency dynamic pressure transducer is specially designed for this purpose. It adopts German HELM made high – performance chip, using micro machining technology to make the integrated silicon chip small effective dimensions, and high intrinsic frequency. It features good elastic mechanics characteristics, of which comprehensive perform is better than that of piezoresistive dynamic pressure sensor. It is ideal for dynamic pressure measurement.
