ABSTRACT:
Short term creep compensation for load cells, platform scales, bench scales and the like is achieved by introducing a thermo-couple in series with one of the output leads from the load cell and utilizing an amplified output signal derived from the original output signal to generate heat which is transferred to a terminal or both terminals of the thermo-couple. The thermo-couple provides a compensating signal which is equal and opposite to the output drift resulting from the creep characteristics so that the final output signal is fully compensated. Proper generation of the compensating signal can be controlled by the gain of the amplifier, polarity of the input signal to the amplifier, and the transfer characteristics from the heater to the thermo-couple terminal.
