Introduction

In an industrial situation where it is required to measure and control some aspect of a process, it is often the application of the knowledge and the ingenuity of the Engineer or Technician which is relied upon to solve the measurement and control problem. Therefore a fundamental understanding of the principle of operation of a range of sensors/transducers and instrumentation techniques applicable in an industrial situation combined with a working knowledge of Process control techniques and tuning methods equips the Engineer or Technician with the necessary skills and makes them invaluable in their workplace

The attendees will investigate the concepts of instrumentation and measurement and will acquire the knowledge relating to the characteristics and properties of the variables being measured. Moreover, the delegate will gain an understanding of the Process control systems and methods used in a modern industrial system

This is a practical and hands-on course and where applicable, theoretical studies will be supplemented with practical activities where the delegate will have the opportunity to design, develop, build, test and evaluate their own instrumentation systems

Some of the main topics covered include:

  • Introduction to Instrumentation systems and Process variables. Symbols and units used and sample calculations
  • Temperature Measurement techniques
  • Strain measurement
  • Investigation of Pressure and Flow measurement
  • Ultrasonic techniques for non-invasive process measurement
  • Practical activities to design, build, calibrate and signal condition a typical sensor application

 

Objectives

The main objectives of this seminar are:

  • To give an understanding of the principles and practice of a range of sensors and transducers
  • By using a hands-on approach, enable the delegate to investigate the operation of an instrumentation system through designing, building and testing typical sensor combined with appropriate signal conditioning circuits
  • To allow the delegate to become familiar and confident with a range of measurement techniques
  • To understand the concepts of Process Control and acquire the knowledge relating to the characteristics and properties of a process variable being measured
  • To disseminate and share experience and knowledge with other delegates through open session discussions hence broadening the knowledge base of all
  • To become familiar and knowledgeable with PID control and develop the ability to ‘tune’ a process control system using PID control
  • To have the confidence and knowledge to apply the above techniques and principles to solve an unfamiliar and bespoke measurement situation in the workplace

 

Training Methodology

The seminar is delivered via a series of mixed activities which will at times involve delegate participation. Theoretical content is delivered by informal lecture and discussion and supplemented where appropriate with tutorial sessions using worked examples. An opportunity is given for delegates to perform their own calculations based on sample systems

An important part of the program is the hands-on aspect. Approximately a quarter of the total time will be devoted to practical activities. Delegates will acquire the skills to design their own instrumentation system from a given sensor(s) and specification and also, using relevant software, acquire the skills to ‘tune’ a process control system

 

Organisational Impact

By attending this seminar the delegate will return to their company more confident in the knowledge and use of sensors and instrumentation systems generally. More specifically, they will:

  • Be equipped with new skills and knowledge which must impact positively within the company structure
  • Be able to evaluate the suitability and application of current in-house instrumentation and control systems and offer guidance and advise on whether such systems may be modified or improved
  • Consequently be able to leverage their skills to potentially cause an increase within the plant or process in term of overall productivity and efficiency through analysis of current systems
  • Be better equipped to advise on new system installations in terms of sensor choice and specification, system monitoring techniques and circuit design
  • Potentially through their newly acquired knowledge be able to advise on in-house design of plant process and instrumentation systems thereby negating or at least reducing the dependency on external agencies and vendors
  • Therefore potentially contribute towards and result in plant and process cost reductions leading to financial savings for the company

 

Personal Impact

The delegate will benefit personally from attendance of this seminar and will enhance their own knowledge base and level of confidence in the area of measurement systems and Process Control Engineering. Specifically the delegate will be able to:

  • Understand the major technologies used in the measurement of flow, temperature, pressure, strain and level
  • Review the construction and operation of the most important sensors and transducers and their application in process measurement systems
  • Evaluate and select the most appropriate sensor technology for a given instrumentation system
  • Design, build and test using a given specification and sensor, their own instrumentation system
  • Identity components and features of a Process control system
  • Calibrate and signal condition the above system and take measurements from the system
  • Understand the limitations of Open loop systems and be aware of the inherent problems associated with Closed loop negative feedback systems
  • Optimise control by tuning a system using relevant software
