内容简介

　　《过程控制仪表技术（第8版）》共分为两部分，第一部分为前6章，作者从人们对生产设备手动操作的实际经验出发，系统地介绍了控制原理、控制设备和控制系统的基本概念。在测量信号的变换和处理方面，把工业仪表中的模拟电路、可编程控制器（PLC）及信号采集系统中的数字电路结合工业电子学中的基本理论融会贯通加以介绍。在测量信号的获取方面，重点对温度、机械量和光学传感器的原理、器件、特性和应用进行丁详细的分析。书中第二部分为后6章，首先讲述了控制信号的类型和执行器，接着重点介绍了离散、连续、计算机及总线网络控制系统的构成、特点和技术指标。结合系统的要求，讲解了PLC的原理和编程方法，位式控制、PID概念及模拟调节器，工业控制计算机硬件、软件的配置等内容。最后介绍了串级和多变量控制系统以及系统的调节质量评定和调节参数的整定方法。
