英语翻译
To accurately control process temperature without extensive operator involvement,a temperature control system relies upon a controller,which accepts a temperature sensor such as a thermocouple or RTD as input.It compares the actual temperature to the desired control temperature,or setpoint,and provides an output to a control element.The controller is one part of the entire control system,and the whole system should be analyzed in selecting the proper controller.The following items should be considered when selecting a controller:

答案

为了能够在无需操作人员过多干预的情况下对过程中的温度进行准确控制,就需要一个以控制器为核心的温度控制系统.这个系统可以接收来自温度感应器或热耦合器的指示温度作为输入,并且将实际温度和设定值进行比较,并将输出送给控制单元.控制器是整个控制系统中的一部分,整个系统设计应当以控制器的选取为重点来进行分析.以下几点是在选择控制器过程中需要考虑的：
