基于MPX2100型压力传感器的高精度数据采集系统

Design Of High Accuracy Data Collecting System Based On MPX2100 Type Pressure Sensor

在压力的测量与分析中,通常压力值的变化速度不快,但要求测量精度很高。本文介绍了一种基于MPX2100型压力传感器的高精度压力数据采集系统,给出了X型硅压力传感器MPX2100以及A/D转换核心部件ICL7135各自的性能特点及其相关接口电路;提供了系统的组成框图、各主要部分电路图及A/D转换软件设计流程图。

In this article, a general system of high accuracy pressure-data collecting which can be further developed and applied is introduced. The function and characteristics of the main component ICL7135 are explained, the frame diagram of the system, circuits of important parts and the progress diagram of the A/D convert program are also given.
