Series MLY torque transducers from Magnova, Inc., Pittsfield, MA, are available with 3.17–4.75 mm dia. shafts for F.S. torque ranges from ±10 to ±250 mNm to ±400 mNm. A central active portion of the shaft, sized for the user-specified measurement range, generates a magnetic field proportional to the transmitted torque which is then converted into an electrical signal by a pair of diametrically opposed Hall effect sensors. Combined error due to nonlinearity and hysteresis is >1% of F.S. range. Transducers accommodate both rigid and shaft-mounted arrangements; torque may be coupled to the transducer shaft via gears, pulleys, and linkages.
