128 channel high-speed data acquisition instrument
128 channel high-speed data acquisition instrument
System Overview:
Based on the user's demand for studying strain collection of large components, our company has developed a new 128 channel high-speed data acquisition instrument. The specifications include: 16, 32, 64, 96, and 128 channels. Adopting the USB3.0 interface format, 128 channels are synchronously collected at a sampling speed of 500kHz per channel, solving the problem of low channel count and sampling speed in the current market for strain gauges.
The DS-128 system is connected to corresponding sensors, which can monitor various parameters such as strain, pressure, temperature, vibration, displacement, voltage, current, etc. in real-time, record and save complete waveform data, making it convenient for users to analyze. Widely used in geotechnical engineering, bridge engineering, aviation and other fields.
