We are putting together a force measurement system using load cells and PC-based data acquisition boards. These components come with NIST traceable calibration certificates. However we have not been able to find a device to provide the excitation voltage and signal conditioning for the load...
Have you considered the effect of putting a reducer between your motor and your load? We typically couple the motor to the load via a gearbox or a set of timing pulleys. In either of these arrangements, the effective torque supplied to the load is increased by the gear ratio. More importantly...
