Analitical results of operation of magnetostrictive torque sensor were shown. A highly linear, little hysteresis and quick response torque sensor was constituted using a two-core multivibrator bridge circuit. Torque sensitivity was improved by adding two diodes between baseemitter electrodes of the two switching transistors in order to discharge the commutation capacitors. An optimal value of the magnetostrictive layer inductance was found theoretically and experimentally to realize a maximum sensitivity of torque sensing.
