The WW-816D Wireless Cable Force Test & Analysis System, with use of independent distributed module structure, specially designed for the cable test of bridge structure. Expanded via wireless WiFi communication, the input signals of cable force of no more than 16 DAQ units can be measured and analyzed wirelessly by a single computer. WW-816D is widely used for the performance testing and analysis of various structure in a variety of fields such as civil engineering, bridge engineering, mechanical engineering.Measurement of fundamental frequency and cable force of cable-stayed bridge, suspension bridge, tied arch bridge and cable in construction.
