Abstract : A torque measuring system based upon a transducer using the magnetostrictive effect of a ferromagnetic material has been evaluated. Required accuracy of the measurement system was plus or minus 1% of reading for a range from 30 to 100% of shaft torque. This accuracy was to be obtained on shafts with metal temperature to 500F and with a system environmental temperature from -35F to +165F. The evaluation was performed in three phases: analysis, design and fabrication, and test.
