Abstract：
The SWJ-V convergence gauge, the first PDA-type convergence gauge developed based on the SWJ-IV convergence gauge, is an automatic measuring product developed using wireless PDA and photoelectric control techniques that features automatically controlled loading and automatic reading and recording. This convergence gauge overcomes the defects of inaccurate loading, the inconvenience of manual recording, and the lack of connection between data and the terminal of the existing convergence gauges, thereby achieving PDA recording and rapid measurement with accurate controlling devices. Accuracy assessments show that the certainty of the SWJ-V convergence gauge reaches a premium level regarding building deformation.
