英文摘要：

This paper analyzed the benefits and drawbacks of precision measuring methods using traditional inductance-transducer signal and the characters of signal transducer. On analyzing of various factors which affect the precision of inductance-transducer, it presented a method to improve precision by using steady-frequency crystal as the signal resource, detecting with single- amplifier absolute value and driving load with the triode power amplify circuit. The correctness and feasibility were verified by experiments.
