its 100 ohm, the problem is that i have lost the datasheet for the strain gauges... So i have no idea of e vs. V, but its a pretty standard strain gauge, with one on each side of the plate so bending moment can be neglected. I guess I need to wire it up together with 2 resistors of 100 ohm to make a half bridge. The problem is that i have no clue which opamp to use and which wire goes where in the halfbridge to get out just the axial force.
Thx for all the help.
