ABSTRACT:
An electronic scale controlling a material feed generates a control signal as the material fed approaches a desired weight. An acoustic tone signal varying in accordance with the control signal and reaching a limiting value when the control signal signifies a zero difference between actual weight and desired weight lets an operator know that desired weight has been achieved.
