摘　　要：This paper describes a new differential extensometer, which has a baseline rod in suspension with both ends free, and some preliminary test results. Compared with a traditional differential extensometer, which has one end of the baseline rod fixed to the ground, this instrument is less affected by commonly encountered interferences ,including environment vibration, momentary power failure, and power noise.This paper describes a new differential extensometer, which has a baseline rod in suspension with both ends free, and some preliminary test results.
