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. Cancoppas Limited has a wide selection of carrier demodulators for use with variable reluctance sensors, LVDTs and even strain gages.
For a discussion describing how to choose the best demodulator for your needs, go here.
