Abstract :
This paper introduced the designing method and working principle of a high precision pressure data acquisition system, which use MSC1210 mcu chip as data acquisition processing center. This system used pressure sensors to collect signals and used multiplexer to switch signals. After PGA signal amplification, Σ-Δ modulation, digital filtering, signal processing, digital or analog output, it communicate with host computer, then achieve information transmission. The Σ-Δ ADC use external voltage reference source to achieve a high precision pressure data acquisition.
