Precision LVDT Signal Conditioning Using LTC1967 Direct RMS to DC Conversion

New Approach to LVDT Signal Conditioning Which Combines an LTC1967 RMS to DC Converter with a Separate Phase Detector Circuit. The LVDT, a Schaevitz E-100 with ±2.5mm of linear range, is driven by a low distortion, amplitude-stable 3VRMS (the manufacturer's recommended amplitude) sine wave on the primary windings of the transformer
