I am developing an application to remove solid waste from a fluid vessel. The greater the motor load, the more waste to be removed, the longer the time the motor runs. Motor current is a continuous signal that can be used. Would a load cell give a more direct and stable feedback to the control? I do not have experience on the type of signal a strain gauge would generate. My limited knowledge of this would be with static measurements at a scale or not very accurate measurements on a moving scale. I would appreciate information on this type of signal.
