Many thanks for your information which is very useful indeed. Apart from strain gauge and load cell, accelerometer is also proposed to register the signature of the model anchorage�s response under the applied impulse.
More specifically, we are about to carry out a research program to investigate the dynamic performance of soil anchorage subject to dynamic impulse in a geotechnical centrifuge, i.e., on a small scale basis (the model anchorage would be 3 mm in diameter). To successfully complete the study, we would require extensive instrumentation and measurement devices.
Presently, we are proposing the following instruments:
1) 30 strain gauges
2) 5 accelerometers (or 10)
3) 5 load cells (or 10)
Totally, 5 model anchorages are to be const
ructed and instrumented, i. e., each of the five model anchorages would be equipped with 1 accelerometer, 1 load cell and 6 strain gauges. However, the model anchorage would be tested dynamically on each individual basis, whilst the other four are also to be monitored during the tests.
For a active model anchorage which is under testing, simultaneous sampling is preferred for the above mentioned 8 sensors to be measured at the same instant in time (Besides, it is also understood that the natural frequency of the model anchorage is estimated to be in the range of several kHz). Whilst for the other four, simultaneous sampling could be less demanding. It would therefore be ideal that simultaneous sampling can be switched among the active testing model anchorages.
It would therefore be much appreciated if you can further advise me on a complete DAQ solution for this purpose. And cost is certainly another major concern as well.
Thanks in advance.
