  • Load cell output correction circuitry
    Patent number: 5031463
    Abstract: Correction circuitry connectable in parallel with a conventional load cell output for compensating for various errors resulting from nonlinearity, creep, and temperature effects. Such circuitry includes an operational amplifier circuit employing the nonlinear characteristic of a diode to create a nonlinear correction signal and an operational amplifier circuit employing a long time constant RC circuit to correct creep.
