现场总线智能变送器温度自补偿功能的实现研究

A study of the realization of the temperature-autocompensation function of a smart Transmitter with fieldbus communication

现场总线智能仪表是现场仪表发展的必然趋势。本文分析了智能变送器温度自补偿功能 ,推导出温度补偿系数矩阵 ,存储在现场总线智能变送器传感器模块存储器中。给出实例分析 。

The fieldbus smart instrument is an inevitable development tendency for fieldworking instruments This paper analyses its temperature auto compensation function and deduces the matrix of the temperature auto compensation coefficient,which is stored in the corresponding EEPROM of the smart transmitter module.The analysed results show its temperature stability is enhanced markedly.
