It is a system that automatically acquires the tube characteristics from the pressure measurement hole to the pressure sensor. It can also be used to verify the frequency characteristics of the pressure sensor.
In pressure measurement on the surface of structures, pressure sensors installed via tubes may be used to measure fluctuating pressure. In this case, the transmission characteristics of the tube, which may not be a significant issue for average pressure, can greatly affect the results. Therefore, it is necessary to understand the transmission characteristics of the tube in advance. To accurately evaluate pressure fluctuations, it is necessary to back-calculate the pressure waveform at the measurement hole from the recorded waveform using the inverse transmission characteristics of the tube. The automatic tubing characteristic acquisition system is a system that can automatically and accurately acquire the characteristics of the pressure measurement tube during experiments in a short time. It consists of a pressure generation device, reference pressure sensor, AD converter, and dedicated software. Additionally, since it can display characteristic values in dB and acquire transmission characteristics between simple voltage inputs and outputs, it can also be used for measuring characteristics of filters and other devices. We offer standard types, standard types with extended options, and large types. For more details, please contact us or refer to the catalog.
