Factory Automation and Manufacturing Machines.Industrial Electronics, Process Control Instruments, Indicators, Controllers and Data Loggers. SCADA, HMI and PLC. M2M and Device Networking, Electrical Controls, Tools, Sensors, Actuators, Motors, Motion Control. Industrial Equipment. Temperature, Humidity, Pressure, Flow and Level.
This blog will cover Industrial Automation and Process Control concepts and firms. You will also find related mechanical and electromechanical components and systems used in automation. In Automation we have Industrial and Machine Automation. A closely related subject is Home and Building Automation that includes HVAC.
Then we have Energy Automation which is used to deliver and maintain power to Homes, Offices and Factories. Many Instruments and Control Panels in these Three Sections are closely related. In this blog Instruments and Equipment in all these three subjects could be covered.
Closed Loop Control Systems
A Closed Loop Control System is the most important aspect of Maintenance, Regulation and Stability in any Live Process. Nature itself is self regulated in an intricate fashion, a keen observer can notice the subtle controls. In Human Created Industrial systems we have Process control as a complex science. We can start by understanding a Simple One.
Process Control Application Notes
When you fill a Bucket with water, You keep an eye on the Level of water, as you open the Analog Tap, which is an equivalent of a Motor operated Valve. Your Eye is an advanced Optical Sensor, which is able to sense the level by the computation in the brain, which in turn operates the muscles of your hand, thru the nervous system. The hand along with the Water Tap is is the Actuator. As the water fills up close to the top, you start reduction of the water flow and keep observing, then as it tops up, you tweak the tap to a trickle. When it reaches the limit you shut off the tap.
While you are half way filling the bucket, what happens if you take a short nap, or a friend comes by and you are get absorbed in conversation, the water overflows and goes waste. Then someone raises an alarm after the Runaway process happens. This is of minor consequence, but it is not so in the case of Temperature, Pressure and also many common systems like the driving of an Automobile. Remember the gears, brakes, accelerator to control and steer the car to the correct destination, a Runaway Process causes an accident.
