Variable reluctance
sensors such as the DP15, DP45 or DP103 require a carrier demodulator.
The carrier demodulator provides the required AC excitation and
receives the AC signal from the sensor and converts it to a useful
DC signal or indication. Validyne has a wide selection of carrier
demodulators for use with variable reluctance sensors, LVDTs and
even strain gages.

to choose the best demodulator for your needs, go here.
