Abstract： |
A method for measuring both axial and radial displacements of rotary shaft includes setting rotator and stator on rotary shaft to be measured to form displacement measuring transducer, making stator be circular iron core with tooth shaped probe on internal ring, winding coil of each probe in self-conduction way, calculating out axial displacement at X direction and radial displacement at X direction of rotary shaft according to parameters of air-gap magnetic conductivity and total number of turns on coil as well as magnetic pole width of probe . |
