PROBLEM TO BE SOLVED: To provide a measurement controller capable of inputting data from a sensor in synchronization with a measurement position of an object to be measured. SOLUTION: The measurement controller is equipped with an analog input circuit 13g which inputs analog data from a displacement sensor 24; a first counter 30 which counts based on pulses from an encoder 23; and a second counter 31 which is arranged in parallel with the first counter and composed of a ring counter counting the pulses. An MPU 13a recognizes a measurement start position of the object to be measured, based on a counter value of the first counter. Furthermore, when the MPU receives an interruption instruction generated based on a counter value of the second counter, it stores analog data acquired by the analog input circuit into a data memory during its interruption process.
