A Structural Displacement Measuring System

摘要

High performance data acquisition and data processing system are demanded in today's science and research. In a multi-channel structural displacement measuring system, high sampling rate and wide dynamic range are highlighted. The design given here uses four analog digital converters (ADC) incorporating with one digital analog converter (DAC) connected as a divider to obtain 24-bit resolution. The ADC/DA C design are introduced by taking displacement logging & processing an example.
