Abstract: PROBLEM TO BE SOLVED: To conduct precise measurement of linear shift movement by making configuration so as to make a primary current constant under a no-load condition of a secondary coil. SOLUTION: A quantity-of-displacement detector 2 has primary coils 5, 6 of an equal number of turns arranged so as to set a common coil axis, connected in series in the reverse directions, and connected to the output side 8 of an amplifier 9 to be an AC voltage source.

A secondary coil 11 fixed between the primary coils 5, 6 is arranged coaxially with their common coil axis, and a resistor R and a capacitor C are connected to its terminals and form a load for the quantity-of-displacement detector 2.  In this case, the load produces a specified relation between the input current of a measuring apparatus and a position of movement of the core 12, since configuration is so made that a current flowing in the primary coils 5, 6 may be constant under a no-load operating condition of the secondary coil 11.
