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 pose much of a problem for average pressure, can significantly 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 pressure measurement tubes in a short time during experiments. It is composed of a pressure generation device, reference pressure sensor, AD converter, and dedicated software. Additionally, it can display characteristic values in dB and can also acquire transmission characteristics between simple voltage inputs and outputs, making it useful 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.

There are two series available: the "integrated type," which has an electrode box built into the main unit, and the "separate type," where the main unit and electrode box are separated. The separate type is ideal for measurements in shielded rooms and various laboratories. The integrated type is a 1-channel version, while the separate type is an 8-channel version. Due to the card-type amplifier unit, it is possible to reduce the number of cards implemented while keeping the cost down and maintaining expandability. This is a bioamplifier specifically designed for research in industrial product development, animal experiments, and psychotechnology. Since it is for research purposes, it does not target specific biological signals, offering a wide amplification range from 500 to 50,000 times (with the separate type reaching up to 100,000 times), and is equipped with multi-stage high-pass filters and time constants. It is optimal for the analysis and evaluation of biological signals in fields such as ergonomics, psychotechnology, and basic medical research.
