Indicators and controllers are fundamental components of process control systems used in various industries to monitor and regulate process variables such as temperature, pressure, flow rate, level, and other parameters. They play a crucial role in maintaining optimal process conditions, ensuring safety, and achieving desired production outcomes.

​

Indicators, also known as process indicators or display panels, provide visual representation of process variables. They typically feature a digital or analog display that shows the current value of the measured parameter in real-time. Indicators allow operators and technicians to quickly and easily monitor process variables and make informed decisions based on the displayed information.

​

Controllers, on the other hand, are devices responsible for regulating and maintaining the desired setpoint or target value of a process variable. They receive input signals from sensors or transmitters that measure the process variable and compare it to the desired setpoint. Based on this comparison, controllers generate output signals to actuate control elements such as valves, actuators, or heaters, to adjust the process variable and bring it back to the desired value.

Controllers can be categorized into various types, including on-off controllers, proportional controllers, integral controllers, derivative controllers, and more advanced control algorithms such as PID (proportional-integral-derivative) controllers. These controllers employ different control strategies to achieve accurate and stable control of the process variable.

​

Indicators and controllers are often combined in a single device known as an indicator-controller or control panel. This integrated unit provides both visual display of the process variable and the capability to adjust and regulate the process through the controller.
