Patent ID: 7878074

Claim:
A differential load sensor comprising; an eccentric sensor, wherein a bending mode of said eccentric sensor measures a first and second eccentric or non-concentric load; a first strain gauge placed on a first surface coupled to said eccentric sensor capable of providing a first signal representative of a deflection of the first surface caused by the bending mode of said eccentric sensor due to the first eccentric or non-concentric load; a second strain gauge placed on a second surface coupled to said eccentric sensor capable of providing a second signal representative of a deflection of the second surface caused by the bending mode of said eccentric sensor due to the second eccentric or non-concentric load; and signal means, receiving the first signal and the second signal, for generating a differential signal representative of a difference in the first signal and the second signal, whereby the difference in the first and second eccentric or non-concentric loads or pressures is detected.
