PID loops are a central component of modulating boiler control systems with applications ranging from basic steam header pressure control to cascading 3-element drum level control. A modern ...

Self-regulating systems with feedback loops, i.e., the routing back of the output of a system to its input, have existed since antiquity and have since become an integral part of modern technology.

Unlike competitive models that must be ordered with functionality factory installed, Red Lion's PAX2C PID controllers offer flexible PID control options for process and temperature applications that ...

A few weeks ago, I installed an automatic water heater switch to my bathroom, but it was a crude device. What I really want to do is design a universal heater driver. That basic idea can be adapted to ...

Looking back through the history of automation, it’s not difficult to see how most advances are extensions of existing technologies. This can be seen at all levels of automation—from the evolution of ...

Consider the features and typical applications for industrial controllers to understand what type of controller fits each application. Do you need a programmable logic controller (PLC), programmable ...
