Abstract
The present invention is a loss-in-weight feeding system including an accelerometer for detecting extraneous disturbances impinging on the system and preventing the disturbance from adversely affecting the feed rate. A split-beam weighing assembly senses the weight of the material in the container and produces a first signal to control the feed rate. The accelerometer is mounted on the split beam assembly and produces an acceleration signal. The acceleration signal is compared with a predetermined limit, and if the comparison shows a difference beyond a predetermined size, the action of the first signal is inhibited.
