Instrumentation and control engineering

Instrumentation is defined as the art and science of measurement and control of process variables within a production or manufacturing area.[1] The process variables used in industries are Level, Pressure, Temperature, Humidity, Flow, pH, Force, Speed etc. Control engineering or control systems engineering is the engineering discipline that applies control theory to design systems with desired behaviors.Control engineers are responsible for the research, design, development and control devices/systems, typically in manufacturing facilities and plants The practice uses sensors to measure the output performance of the device being controlled and those measurements can be used to give feedback to the input actuators that can make corrections toward desired performance. When a device is designed to perform without the need of human inputs for correction it is called automatic control (such as cruise control for regulating a car's speed). Multi-disciplinary in nature, control systems engineering activities focus on implementation of control systems mainly derived by mathematical modeling of systems of a diverse range.

Instrumentation and Control Engineering

This term refers to the graduate discipline which many universities provide at graduate and postgraduate level.Instrumentation and Control plays a significant role in both gathering information from the field and changing the field parameters, and as such are a key part of control loops.The Instrumentation Technology, being an inter-disciplinary branch of engineering, is heading towards development of new & intelligent sensors, smart transducers, MEMS Technology, Blue tooth Technology. This discipline finds its origin in both electrical and electronics engineering, and it covers subjects related to electronics, electrical, mechanical, chemical and computing streams. In short, it deals with measurement, automation and control processes.In today's scenario, there are many people who are willing to make a career in this stream. Almost all process and manufacturing industry such as steel, oil, petrochemical, power and defiance production will have a separate instrumentation and control department, which is manned and managed by instrumentation and control engineers. “Automation is the buzz word in process industry, and automation is the core job of instrumentation and control engineers. Hence, the demand for instrumentation will always be there.

Nature of Job

An instrumentation and control engineer is required to
  1. Design and develop control systems
  2. Maintain the existing control systems
  3. Manage the control systems
  4. Collaborate with design engineers, purchasers and other staff members involved in the production processes
  5. Manage projects within the given restraints including cost and time
  6. Troubleshoot
  7. Ensure that the instruments comply with health and safety regulations
  8. Ensure that quality standards are maintained
  9. Provide consultancy support

Requirement

Instrumentation and control engineers have a role to play in all the fields where there is automation.The instruments created by control engineers to automate the processes,thus reducing the involvement of manpower.
An instrumentation and control engineer is expected to learn subjects like
Knowledge of PLC programming, Panel view HMI screens, SCADA Application programming preferred.

Goal of Instrumentation and control engineer

Instrumentation and control engineers works with the goal of improving
  • Productivity,
  • Optimization,
  • Stability,
  • Reliability,
  • Safety,
  • Continuity.
These engineers design, develop, and maintain and manage the instruments and the instrumentation system

PROFIBUS

 PROFIBUS PROFIBUS or Process Field Bus was introduced in 1989 and it is sometimes confused with PROFINET. It links plant automation modules with the process control. PROFIBUS uses a multi drop single cable to connect the devices. This method is cost effective especially for larger sites when compared to old methods. Its installation cost is low and it is easy to find faults as well because it is a single cable. Types of PROFIBUS There are two types or versions of PROFIBUS commonly known as 1.    PROFIBUS DP 2.    PROFIBUS PA Here is a brief introduction to both of these types. PROFIBUS DP It runs over two core screened cable that is violet sheathed and its speed varies from 9.6Kbps to 12Mbps. A particular speed can be chosen for a network to give enough time for communication with all the devices present in the network. If systems change slowly then lower communication speed is suitable and if the systems change quickly then effective communication will happen through

The Industrial Safety Systems and Their Types Industrial automation has minimized the human interaction with the machines but has not completely eliminated it. Industrial safety systems are introduced to protect the human who work in hazardous plants. Some examples of these are oil and gas, chemical and nuclear plants. The industrial safety systems not only protect the humans but also protect the environment and the plant itself from the chemical reactions. These systems do not control any process but in fact come into play when it is not possible to control a process through normal means. They are rather installed as a protective measure and are quickly becoming the need of every working environment. There are various types of safety systems in place and their use depends on the type of industry they are used in. Here is a look at some of them. Process Control Systems (PCS) They are installed for the monitoring of the manufacturing environment and they control the manufact

Large-scale, reliable, next-generation plant-wide field wireless system A new architecture for our “Grow” concept Yokogawa launched the world’s first wireless field products conforming to the ISA100.11a standard in 2010 and has led the business ever since. Now, Yokogawa has released a new, large-scale, reliable, next-generation plant-wide field wireless system. In developing this system, which forms the core of field digital solutions, Yokogawa has focused on the following three key features. 1. Reliability: reliable high-performance field wireless and redundant technologies 2. Flexibility: flexible architecture that supports the full range, from small to large-scale plants 3. Openness: open ISA100.11a standard that allows third-party field wireless devices to be connected This new system has been developed in line with Yokogawa’s “Grow” concept of helping customers to grow and enabling ourselves to evolve and continue to offer timely solutions.  →The individual spec
