A position sensing feedback wireless transmission system comprises: a movable carrier, a sensing head, a scale and a display or a controller. When the present position of the movable carrier is required to know, the sensing head can be utilized to transmit the measured information data back to the display or the controller in wireless manner. Since the position sensing feedback wireless transmission system of the present invention adopts the wireless technology, in addition to save the connecting wires cost, it can be relatively simply used in the machine. Consequently, for the design of the mechanism required to measure the long distance, the unit with a plurality of running wires can be dispensed with.
