JC690 High- frequency Dynamic Pressure Transducer

●Product Overview

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. This requires that the pressure sensors used have high intrinsic frequency, very short rise time, and wide and good response frequency band to ensure sufficient dynamic pressure measurement accuracy. JC690 high-frequency dynamic pressure transducer is specially designed for this purpose. It 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. It boasts good elastic mechanics characteristics and its comprehensive performance is better than that of piezoelectric dynamic pressure sensor. Thus, it is ideal for dynamic pressure measurement.
