High frequency pressure transmitter applicable fields:
In military engineering, chemical explosion testing, petroleum exploration and well testing, materials, mechanics, civil engineering, and geotechnical engineering. In scientific experiments such as trauma medicine and hydraulic power mechanical testing, as well as modern instruments and meters, it is necessary to measure dynamic pressure waveforms with high frequency changes, fast and steep pressure waveform rise, amplitude, and effective value without distortion. This requires pressure sensors to have high natural frequency, extremely short rise time, and wide and excellent response frequency band to ensure sufficient dynamic pressure measurement accuracy.

Selection Tips:
1. The output frequency of the product can be sorted into three items (H1, H2, H3), and users can determine the most suitable output frequency range according to industrial and mining requirements, making product selection more economical.
When installing flat membrane products on site, the correct sealing method should be used to prevent installation stress from affecting product stability.
Select the additional function code "E" for intrinsically safe explosion-proof Ex iaIICT5, which must be powered by a safety barrier.
