TABLE OF CONTENTS Measurement and control is the brain and nervous system of any modern plant. Measurement and control systems monitor and regulate processes that otherwise would be difficult to operate efficiently and safely while meeting the requirements for high quality and low cost.
Process Measurement and Control (also known as Process Automation, Process Instrumentation and Control, or just Instrumentation) is needed in modern industrial processes for a business to remain profitable. It improves product quality, reduces plant emissions, minimizes human error, and reduces operating costs among many other benefits.
The production quantities and requirements define the type of process required to make a certain product. In the process industries, two types are commonly used: continuous process and batch process. Often, a combination of the two processes exists in a typical plant.
The continuous process consists of raw materials entering the process and following a number of operations emerge as a new product. The material throughout the process is in constant movement and each operation performs a specific function.
The batch process consists of raw materials transformed into a new product according to a batch recipe and a sequence. The raw materials typically are fed into reactors or tanks where the reactions occur to produce a new product.
automation A system or method in which many or all of the processes of production, movement, and inspection of parts and materials are automatically performed or controlled by self-operating machinery, electronic devices, and so on.
