随着挤出产品的产量和质量不断提高，对温度的精确测量和控制比以往任何时候都更加重要。本章一般性地描述了测量温度、加热和冷却系统的技术以及闭环控制的概念，然后对比了传统的和微处理器的实现。由于更严格的要求要求将过程控制方案应用于挤出，因此不可能单独考虑温度问题。因此，讨论了挤压工厂的总体控制系统，并最终尝试展望未来。
The increasing demands of obtaining greater throughput with increased quality from extrusion products have made accurate measurement and control of temperature more important than ever. This chapter describes in general terms techniques of measuring temperature, heating and cooling systems, and concepts of closed loop control and then contrasts conventional and microprocessor implementations. Since the more exacting requirements demand that process control schemes be applied to extrusion it is not possible to consider the temperature problem in isolation. Therefore a total control system for an extrusion factory is discussed and finally an attempt is made to look into the future.
