Objectives

• The main objectives of this seminar are:
• To give an understanding of the principles of operation 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 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
