The "SENJAS-SP / MP" is a multi-point pressure sensor with good response characteristics. It is also possible to install a low-pass filter card inside the sensor. By combining the common AD converter for SENJAS, the multi-point pressure measurement software SENJAS-P, and the automatic calibration option SENJAS-CAL, measurement accuracy can be improved by approximately twice. Configurations of up to 1344 channels are possible. It can be used for various applications such as wind tunnel experiments and pressure measurements in vehicles. "SENJAS-SP" In addition to the 32-channel unit, there is also an 8-channel unit, allowing for smaller configurations. The use of sensor sockets and interchangeable tube ports makes it easy to change tube sizes and sensor configurations. Maintenance costs and durations can also be significantly reduced. Configurations and expansions in units of 1 channel are possible. Each channel has an independent amplifier, and the power supply section is also independently structured to prevent any impact on other sensors in case of a sensor chip failure. It is also possible to store it in a compact EIA rack for multi-channel configurations. "SENJAS-MP" This series is mainly focused on space-saving. Up to 4 or 8 32-channel cards can be stored within a case. It has about two-thirds the volume of the SENJAS-SP.

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.

This system is a data recording and analysis software specifically designed for wind pressure experiments. It allows for the acquisition of multi-channel pressure data along with reference signal data such as wind speed, wind pressure, and rotational speed. It can perform both average wind pressure measurements and fluctuating pressure measurements. The Windows-based software features automatic calibration using sensors and calibrators from Melon Technos, a frequency correction function to adjust tubing characteristics, engineering value conversion considering the bilinear characteristics of the sensors, and various analysis functions. Additionally, it is possible to build a user-oriented measurement system that integrates with control systems and enables fully automated measurements through the Melon Technos library, which can be called from command procedures, various programming languages, and other development tools. The software comes standard with real-time pressure waveform and color contour displays, tubing correction, and spectral analysis functions.
