Abstract
The authors present a novel technique of dual secondary coils for self-compensation of a linear variable differential transformer (LVDT) transducer for variations in excitation current and frequency and changes in ambient and coil temperatures. Experiments on compensated LVDT exhibited high sensitivity, good linearity, insensitivity to variations in excitation current and frequency, and self-compensation for changes in temperature. The transducer is suitable for both favorable and hostile environmental conditions for parameter acquisition and data handling
