What signal conditioning is required for LVDT/RVDT position sensors?

LVDT/RVDT signal conditioning: excitation (sine wave typically 1-10 kHz at 1-10 Vrms), signal demodulation (extract position information from AC output amplitude and phase), ratiometric measurement (divide differential by sum for temperature stability), filtering (remove carrier frequency, pass position signal), and linearization if needed. Modern signal conditioners integrate all functions with DC output (4-20 mA or 0-10 V) proportional to position. Consider: excitation frequency vs sensor bandwidth, synchronous demodulation for noise rejection, and auto-balance or auto-zero for offset correction. AC outputs require phase-sensitive detection to determine direction.
