C050010715A pressure sensor (0-25 bar)
product description
In military engineering, chemical explosion testing, petroleum exploration and well testing, materials, mechanics, civil engineering, geotechnical mechanics. In scientific experiments and modern instruments such as trauma medicine and hydraulic power mechanical tests, it is necessary to measure some dynamic pressure waveforms, amplitudes, and effective values with high frequency and rapid pressure rise without distortion. This requires high pressure sensors. Natural frequency, extremely short rise time and wide and excellent response frequency band to ensure sufficient dynamic pressure measurement accuracy, HM90 high frequency dynamic pressure transmitter is designed and developed for this purpose, it uses the high performance of German HELM company The chip uses micro-machining technology to make the integrated silicon wafer small in effective size and high in natural frequency; it has excellent elastic mechanical properties, and its overall performance is superior to that of piezoelectric dynamic pressure sensors, making it a good choice for dynamic pressure measurement.
