Abstract
A torque sensor having an array of four saturable core magnetic flux detectors arranged in two pairs. Each pair of flux detectors is associated with a pair of magnetoelastic bands. A triangle signal is applied to one end of each pair of flux detectors and an offset correction voltage is applied to the opposite ends. Two amplifiers are associated with each pair of torque detectors and are responsive to the second harmonic of detected flux signals. The signal conditioning electronics provide automatic offset and drift correction.
