RVDT angular displacement sensor with adjustable sensitivity

The invention provides a RVDT angular displacement sensor with adjustable sensitivity which comprises a rotating shaft and a rotating shaft sleeve, wherein a rotor lamination is fixedly arranged on the rotating shaft, and a stator winding and an excitation winding are fixedly arranged at the positions, corresponding to the rotor lamination, of the outer wall of the rotating shaft sleeve; and also comprises a magnetic flux gathering sleeve assembly which comprises an outer sleeve and a magnetic flux gathering inner sleeve which are fixed to each other, and the outer sleeve is in threaded connection with the outer wall of the rotating shaft sleeve, so that the magnetic flux gathering sleeve assembly can axially move on the rotating shaft sleeve. According to the invention, the output sensitivity of the RVDT angular displacement sensor can be adjusted, the problem of inconsistent sensitivity of the RVDT angular displacement sensor is solved, and the problems of difficult assembly and adjustment process, inconsis
