资料介绍

DDS-11A型电导率仪是一款测量水溶液电导率的高性能仪器,其缺点在于不能实时采集及记录数据。本文以MSP430单片机为核心,设计了一套电导率仪与PC通信的接口电路。该系统具有响应速度快,功耗低,使用USB转串口通信等特点,实现了电导率仪大量数据采集的自动化,提高了实验的效率。

Conductivity meter DDS-11 A is a high-performance instrument for measuring solution conductivity,but its disadvantage is that the meter cannot be real-time acquisition and record data. MSP430 single chip unit is taken as the core,an interface circuit is designed for communication between the conductivity meter and PC. The designed interface circuit system has the advantages of quick response,low power consumption,and can use USB for serial communication. By using the designed system,the data measured by conductivity meter DDS-11 A can be real-time acquisition and the efficiency of measurement can be greatly improved.
