33-, Abstract of the Disclosure, INDUCTIVE COIL STRUCTURE An apparatus if provided for use with, non-contacting torque sensors. Many non-contacting torque sensors use bulky inductive coil structures to induce magnetic flux into the shaft whose torque is to be measured, and to sense a change in magnetic permeability of the shaft in response to torque applied thereto. These large, cumbersome structures are quite expensive to fabricate, and difficult to manufacture and install. As a solution a flexible, ribbonlike inductive coil structure is provided. The dual layer construction of this coil structure enables it to provide adequate magnetic flux distribution, similar to that of much larger …
