Abstract
An a.c. generator is electrically connected to an exciting coil unit to supply alternating current to the exciting coil unit. A sensing coil unit is electromagnetically coupled to the exciting coil unit via ferromagnetic material of a shaft. An electrical signal induced across the sensing coil unit varies as a function of torque on the shaft. A balancing member electromagnetically coupled to the sensing coil unit includes a removable segment to zero-adjust the electrical signal when no torque is applied to the shaft.
