Introduction: DM-YB1808/40/60 type dynamic and static strain test system is suitable for measuring the strain stress of the structure and various other physical quantities, such as force, pressure, load and torque. It is especially suitable for teaching, model experiments and strain testing of various engineering sites in geotechnical, structural, bridge, vibration test benches, etc. The system can collect and display 20 channels of data at the same time, and can cascade multiple units to improve data acquisition channels. The acquisition system is equipped with the display software of the upper computer. The data storage format is dat format, which can be imported into Excel. The maximum acquisition speed is 10hz and 40hz. (40hz speed means that 40 sets of data are collected in one second when all channels are collected at the same time). Features: 1. Using 24-bit high-resolution AD conversion chip, the data is stable and reliable; 2. Realize the conversion of full-bridge, half-bridge, quarter-bridge measurement by shorting the shorting piece; 3. Channel independent design, each channel is connected to different types (full bridge, half bridge, quarter bridge) sensors to collect data at the same time. 4. The system has a USB interface, which can be collected online with a general-purpose computer; 5. The same type of system has the function of multi-machine series connection, and the maximum can be connected in series to 32 units. 6. The configuration of GPRS wireless module can realize wireless transmission nationwide, and the configuration of lithium battery can realize the collection of on-site no-power conditions 7. It can realize the automatic data storage of U disk.
