A question about amplifying low level strain gauge voltages
The manual is here and quick start guide is here.

It appears that the full scale range is configurable using their software.
Minimum differential appears to be +/- 2 mV or maybe less.
ir IF this is correct and IF your strain gauge outputs about 1 mV max then the V-Link 200 should be all you need. A closer reading of the manual and a look at the software manual should clarify this.
