Displacement sensor for industrial measurement

The displacement sensor for industrial measurement comprises an outer frame, vertical grooves are formed in the front side and the rear side of the circumferential side face of the outer frame, vertical frames are fixedly installed in the vertical grooves, and detection rods are arranged at the centers of the vertical frames. According to the device, the clamping blocks are pulled to move, the rubber sheet is pulled in the process that the multiple clamping blocks are separated from one another, a detection piece with a mark is placed in the space among the multiple clamping blocks, the pulling force on the clamping blocks is released, the elastic force of the rubber sheet rebounds, and then the multiple clamping blocks clamp the detection piece; at the moment, the rotating wheels connected with the clamping blocks make contact with the detection piece, the detection piece can horizontally rotate among the multiple clamping blocks through the multiple rotating wheels, the position marked on the surface of the
