摘要: A method and apparatus are provided for measurement of absolute position of a moveable machine member wherein output signals of a plurality of position measuring devices are selectively connected to an interface circuit. Each position measuring device produces output signals representing relative position of a device armature and device stator. The position measuring devices are coupled to the machine member so that the absolute position of the machine member anywhere within its range of motion may be uniquely determined from the output signals. A control signal is produce to control the selection of the output signals to be connected to the interface circuit which, at any instant, receives the output signals of a single position measuring device.
