Red Lion's PID Controllers Help You Meet Specific Process Requirements

Abbreviated as PID controller, a proportional-integral-derivative controller is a control loop feedback mechanism. Globally used in industrial control systems, it works by calculating an error value such as the difference between a measured process variable and a desired set point. The main function of the controller is to minimize the error and to adjust the process using a manipulated variable. In a PID controller algorithm, there are three separate constant parameters. In this context, 'P' denotes the proportional, 'I' derives the integral and 'D' stands for derivative values separately. These values can be interpreted in terms of time: P depends on the present error, I accumulates past errors, while D predicts future errors, depending on current rate of change. To adjust the process, the sum of these three actions is calculated using a control element like the position of a control valve, a damper or the power supplied to a heating element.

A PID controller is considered to be the best device in most industrial control systems. In the PID controller algorithm, the tuning of three parameters helps you control the actions so as to meet specific process requirements. The controller can respond to an error by controlling the degree at the desired set point. These controllers are available in various specification as per your diverse requirements. User-friendly interface, easy installation, non-interrupted functionality and high accuracy are some the recognized features that make these controllers popular in the market.
