随着科技的发展和生产实践日益增长的需要,国外越来越多的工业自动化仪表制造公司,把日益成熟、完善的电子计算机技术推广应用到自动化仪表上,开发出了新一代的智能型仪表,代表了自动化仪表发展的方向。日本横河公司1980年以来投放市场的SLPC可编程调节器,就是一种比较典型的智能型仪表。通过与SPRG编程器配合编程,SLPC就可获得过程所需的各种运算和控制功能。本文对SLPC可编程调节器及其在乙烯
With the development of science and technology and the growing need of production practice, more and more industrial automation instrument manufacturing companies abroad popularize and apply the increasingly mature and perfect electronic computer technology to the automation instruments, and develop a new generation of intelligent instruments , Representing the direction of the development of automated instrumentation. Japan Yokogawa SLPC programmable regulator on the market since 1980, is a typical smart meter. By programming with the SPRG programmer, SLPC gains the various computational and control functions required for the process. This article on the SLPC programmable regulator and its in ethylene
