In direct digital control (DDC) a single computer is able to carry out PID control for multiple loops at the…
Switchgear can be defined as equipment used for controlling, regulating and switching ON and OFF power circuits. Switchgear units range…
Digital PID controllers have replaced most pneumatic and electronic analog controllers in industrial control applications. Digital PID controllers are preferred…
Process and Instrument Diagrams (P&IDs), also called Piping and Instrumentation Diagrams and Loop diagrams are construction and documentation drawings that…
RF system’s output power level is often the key factor in the design and ultimately the performance of virtually all…
In some processes, it is a common requirement for two flows to be kept in precise ratio to each other…
The reed like contacts of a reed relay are encapsulated in a small sealed glass tube that is evacuated or…
Feedforward control is based on principle of pre-emptive load counter-action i.e. if all major loads (i.e. disturbances) on a process…
We know very well that closed loop control provides increased performance over open loop control. So it would be rational…
