單回路控制器
單回路控制器用於多種工業設施，例如發電廠、煉油廠、石化廠、化工廠和鋼鐵廠。這些控制器從傳感器接收溫度、流量、壓力和其他類型的測量讀數，並向閥門等控制元件發送相應指令，以便將這些值保持在期望範圍內。每個控制回路都有單獨的控制器。如今，單回路控制器廣泛應用於工業領域，用於控制小型工廠設施並用作集散控制系統的備用設備。

Continuous technology improvement is ongoing in the pulp & paper industry to obtain the best possible performance. The improved plant performance translates to the higher quality improvement and lower cost, and simultaneously environmental friendly plant operation.
Automated control of industrial boilers is an excellent application for YS1700 microprocessor-based loop controllers. These instruments can be programmed to perform the operations of plant master, boiler master, fuel and air control with oxygen trim and drum level/feedwater control.
In process control it is not uncommon for systems to be affected by dead times, due to material transfer times. This is evident typically in pipelines. A fluid of density ρ and flow rate w in a section of pipe A the length of d takes the amount of time τ = ρAd/w to cover the whole distance (see Figure 1).
