Single Loop Controllers

Single loop controllers are used in a variety of industrial facilities such as power plants, oil refineries, petrochemical plants, chemical plants, and iron and steel plants.  These controllers receive temperature, flow rate, pressure, and other types of measurement readings from sensors and send corresponding instructions to control elements such as valves in order to maintain these values within a desired range.  Each control loop has its own controller.  Single loop controllers are widely used in industry today to control small plant facilities and serve as back-ups to distributed control systems.

  • YS1310

    The YS1310 Indicator with Alarms is an input indicator that has alarms with two inputs. Two loops can be displayed simultaneously. A high limit alarm, low limit alarm, high-high limit alarm, and low-low limit alarm can be generated for each of the two inputs, and the AND connection or OR connection of arbitrary alarms can be output from a total of 6 contacts.

Overview:

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.

Overview:

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).
