Rotating Torque Sensor, Type 4501A… Description Mechanical Design Torque sensors Type 4501A… comprise a rotating shaft mounted on bearings inside a housing. The shaft has a necked section - called the torsion zone - to which strain gages are attached and connected in a full bridge circuit. Slip rings and brushes provide the link between rotor and housing with two slip rings carrying the electric power supply to the strain gages on the rotating shaft.
