摘要
量热仪是能源生产和能耗企业必备的重要测量仪器,其测量精度和效率直接影响着经济效益。为了提高量热仪的测量精度,整个量热系统的测温精度、准确性、稳定性等诸多方面都需要得到改善和提高。本文给出了采用单片机及铂电阻PT1000为核心器件的高精度恒温式自动量热仪设计。
The catorimeter is an important kind of measurement instrument of sources produce and consumed energy enterprise,and its precision of measurement and efficiency directly exercise influence on economical benefit. In order to improve the precision of measurement of the catorimeter,the precision of temperature measurement and accuracy as well as the stability of the whole system concerned must be improved urgently. In this paper,SCM and Platinum -resistor PT1000 are chosen as its core to design the circuit of the isothermal automatic calorimeter.
