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.
Built-in high sensitive acceleration sensor, small and portable
Up to 16 DAQ units can be extended for parallel sampling
Wireless WiFi communication for up to 200m of communication distance (Visual)
The software-selectable sampling rate up to 1kHz
Powered by intelligent management rechargeable lithium battery pack, up to 8h of battery life (Fully charged)
Support the function of automatic and manual search of cable's vibration base frequency or frequency difference
Support "One-button" visual parameter settings, and the working status of the channel can be displayed in real time
during parameter setting
Application Conditions:
1. The fundamental frequency of the cable can be accurately mesured
2. The stiffness of the cable must not be excessive
3. The slenderness ratio of the cable must not be less than 10
4. The fundamental frequency of the cable base is greater than 10 times the frequency of the cable
In the process of cable force test, if the cable measured does not meet the above conditions, the measurement results will have a large deviation.
