<p>PURPOSE:To realize a highly reliable torque detector by providing two systems of detecting circuit comprising a switching means, a sample & hold circuit, and an output means. CONSTITUTION:Connection at one end of a torque detection coil L1, having inductance variable with torque, is switched through a switching means 13. The transient voltage value, at the time of switching the connection, is samples and held by a sample & hold circuit 14 under control of a control means 12. The transient voltage value is then converted into a signal corresponding to the torque value by an output means 15. The torque detector is provided with two systems of detecting circuit comprising the switching means 13, the sample & hold circuit 14, and the output means 15 and the two systems of detecting circuit are operated alternately by the control means 12.</p> |
