Claim 5:
6. The two-wire displacement sensor device according to claim 1, further comprising:
a waveform shaping unit configured to shape a waveform of the alternating current signal having the voltage waveform output from the LC oscillation circuit,
wherein the first constant current circuit in the interface unit is switched between an ON state and an OFF state based on a pulse signal obtained by the waveform shaping,
or further comprising:
a waveform shaping unit configured to shape a waveform of the alternating current signal having the voltage waveform output from the LC oscillation circuit; and
a frequency dividing unit configured to divide a frequency of a pulse signal obtained by the waveform shaping,
wherein the first constant current circuit in the interface unit is switched between an ON state and an OFF state based on the pulse signal whose frequency is divided.
