Instrument for measuring pressure pulsations
Thread Content
I work in pump testing, and the task requires measuring pressure fluctuations. The commonly used pressure sensor for this purpose is the Rosemount 3051 model; however, it is unable to measure transient pressures and has an insufficient response time. Therefore, I need to purchase a different sensor. The highest pressure I need to measure is 42 MPa. I found online that a \"high-frequency dynamic pressure sensor\" might be suitable for this purpose, and I discovered an American company that manufactures such sensors. I’m not sure if the information is correct. Have any friends who have conducted measurements in this area? I’d like to ask some questions about it. Thank you so much!
Thank you. Since I’m not very familiar with this, I can only provide a rough description of the requirements. The medium to be measured is water, and the measurement is taken at the pump’s outlet. By adjusting the valve opening, the pressure can vary between 18 and 40 MPa. However, when the pressure reaches a certain value, the system operates for a certain period of time during which the pressure fluctuations are relatively small, not exceeding 3%. It is required that data be output at a rate of no less than 1000 times per second. I’m not very familiar with the parameter of frequency response; the technical requirements ask me to provide curves of pressure over time, and I’m still not clear about this. Could you please provide more information on this topic? Thank you
:victory: Learned it* – and it still occurs with such high frequency!
