摘要： The present invention relates to a linear displacement transducer with improved accuracy, in which stable contact is achieved by forming contacts coming into contact with resistors in a elastic linear contact type, rather than a conventional point contact type, using a rotating roller made of a conductive rubber material, and the life span thereof is extended by considerably reducing friction. The linear displacement transducer with improved accuracy, in which the displacement of an object is measured depending on resistance values measured on contacts in contact with a thin film A having a zero electrical resistance value and a thin film B having an electrical resistance value RL and being parallel to the thin film A, includes a conductive rotating roller connected to one end of a moving shaft, adapted to rotate in conjunction with the movement of the object and configured to form linear contacts while being in contact with the thin films A and B, and the average of electrical resistance values, which are generated by the linear contacts formed by the rotation of the rotating roller, is measured as displacement.
