Process List few examples of Process Industries. Process Control Process control refers to the techniques used to regulate process variables during product manufacturing.For instance, the ratio of one ingredient to another, the material’s temperature, how well they are mixed, and the pressure at which they are held can all have a big impact on the …
What is 3 Element Control? Boilers in power plants that encounter quick and wide-ranging load variations need three-element control. Control with three elements is quite similar to control with two elements, with the exception that the water flow loop is closed rather than open. In order to determine the feedwater flow’s index or set point, …
What is a Control Loop? The control loops used in the process control industry all function in the same manner, which necessitates the completion of the following three tasks: What are different types of control loops? In industrial operations, two types of control loop systems are often utilised. They are the closed loop system and …
In this article, we will see how to read and interpret P&ID. How to read the Piping and Instrumentation Diagram? The key for understanding Piping and instrumentation diagrams (P&IDs) is We must be familiar with every ISA standard P&ID instrument symbol and standard letter code of process plant instruments and equipment. Try to read some …

A process Flow Diagram (PFD) is a graphical representation of the process industry that defines the relationship between major equipment, process lines, and main control loops of the process industry. The process flow diagram is known as a diagrammatic representation of the mass and energy balance. The PFD serves unit operations in a simple manner …
What is Excitation System? Excitation is the technique of creating a magnetic field using an electric current. An excitation system’s primary job is to supply direct current to the synchronous machine field winding. The excitation system regulates the field voltage and field current to carry out control and protective tasks necessary for the power system …
For most control applications in process industries, it is required to have more than one control valve to respond to the single controller output. The control valves must be configured to follow the control instructions issued by a particular controller. Control valves are said to be split ranged or sequenced and configured to follow the …

What is override control? There could be several dangerous situations in an industrial process plant, because of the unpredictable process conditions which could destruct the operations of the process. During this condition, the normal process must be stopped and maintenance must be started to change the unacceptable situation. In order to do this, we can …

What is the purpose of using a 4-20mA signal in process automation? Industrial automation is carried out by transmitting signals from field devices to the controller and this signal will be a 4 -20mA analog signal. In order to do the transmission of physical signals such as pressure, temperature, flow, and level we need to …
Introduction Hey guys in this session we are gonna discuss about a PLC program for a batch process.In my earlier posts i mentioned the basics of PLC so you can check that out by clicking the link below https://automationforum.co/2018/02/programming-logic-devices-plc.html so lets discuss about the program Procedure Automatically injects the container with liquids A and …
