I note that the SCC SG04 has a 2.5v excitation voltage and the force unit indicated is recommended at 10v excitation.
There is a 10v excitation unit which is the SCC SG24. Anyway with a lower excitation voltage you get less mV output for a force input which could mean that you loose ability to measure the desired force as it would be 4 times smaller than recommended. The smallest force unit is 50lb force full scale. This is quite a lot for pressing a syringe isn't it? An alternative way of looking at this is that you don't get enough resolution in the measurement if you sensor range is too big. I could have the wrong end of the stick for your application? Best advice is to perform a simulation with some wieghts.
