SENSOR DEVICE FOR DETECTING A POSITION IN AN AXIAL DIRECTION OF A SHAFT MOVING AND ROTATING IN A LONGITUDINAL DIRECTION AND ROTATING, CAPABLE OF MOVING IN A LONGITUDINAL DIRECTION BY USING A SINGLE SENSOR

摘要

PURPOSE: A sensor device for detecting a position in an axial direction of a shaft moving and rotating in a longitudinal direction and rotating is provided to easily perform a translational motion and a rotational motion of a rotatable shaft and to simply detect an axial direction and position of the rotatable shaft.;CONSTITUTION: A sensor device(1) for detecting a position in an axial direction of a shaft(2) moving and rotating in a longitudinal direction and rotating comprises a linear sensor(3) and a transmitter element(4). The linear sensor is arranged to be parallel to the shaft in a longitudinal direction of the shaft. The linear sensor comprises two or more sensor elements(5). The transmitter element is constituted so that a clear measurement signal change is generated in at least a single sensor element among sensor elements capable of individually measuring.;COPYRIGHT KIPO 2012
